Published: November 2019

Abstract
The Weixinan sag in Beibuwan basin experienced strong tectonic movement during late Oligocene, which formed a number of fault-block and fault-nose structural traps. The fault sealing ability, especially the fault lateral sealing ability, plays an important role in the process of structural trap accumulation. The fault lateral sealing ability mainly depends on the AFPD between the material in the fault zone and the target plate. This paper considers the contribution of two fault plates to the muddy content of the fault zone and quotes the geological model of Rm, which can quantitatively evaluate the fault sealing ability. Through analysing the shale content (Rm) and mudstone smear factor (SSF) of the drilled wells of the Member 3 of Weizhou formation in A oilfield, the quantitative chart of Rm-SSF is established. A quantitative prediction technology of the fault sealing oil column height is established by using the principle of the equilibrium between the appearance of fault press difference (AFPD) and the parallel stratigraphic phase of the resultant force. This paper applies the quantitative analysis technology of the fault lateral sealing ability to the A oil field in the WeiXinan sag, and solves the problem why the oil-water interface of each fault block is inconsistent in the A oil field.

Authors: Zhang Yang , Zhang Hucai 
Published: November 2019

Abstract
Lake Yangzong, one of nine lakes in Yunnan Province, has experienced both steady and instantaneous inputs of heavy metals during the past several decades. During this study, the chronology of lead (Pb) pollution was analyzed by extracting a 60 cm long sediment core from the center of the lake, dating the sediments using 120Pb and 137Cs methods and analyzing the sediments for lead concentrations. The atmospheric deposition of Pb was predominately related to coal and ore consumption from a nearby aluminum manufacturer and thermal power plant and it may be considered non-point source pollutants. Combining the results of Pb isotopic compositions and Pb concentration and Igeo value, we deduced that the anthropogenic Pb was primarily be attributed to regional emissions from non-ferrous metal production industries.

Abstract
At present, laboratory test and field immersion test are the primary methods to study the collapsibility characteristics of loess foundation. However, the stress state of laboratory test usually does not conform to the actual in-site situation, while the field immersion tests are expensive and difficult to operate. Thus, a new economical and efficient method which can reflect the actual engineering is urgently needed. Centrifugal model test, which is the best physical model test, has been extensively used in various fields of geotechnical engineering. However, centrifugal model test is seldom used in the simulation of collapsibility characteristics of loess foundation. In this paper, centrifugal model tests of natural water content foundation and saturated foundation are carried out for the collapsible loess with strong self-weight collapsibility located in Yili Region in Xinjiang, China. The collapsible deformation of loess foundation based on double-line method is obtained. The results show that the amount of foundation collapsibility simulated by low head saturation method is the closest to that of field immersion test, which verifies the feasibility of using centrifugal model test to simulate collapsible deformation of Loess foundation.

Authors: Bian Menglong , Wang Wencai 
Published: November 2019

Abstract
In order to obtain the distribution law of the temperature field of the vertical airflow, a theoretical model of the wind temperature forecasting of the vertical well is established and simplified on the basis of considering the convective heat transfer and the exchange moisture. The measured error of the theoretical model is between -3.1% and 2% by measuring the variation of air and surrounding rock parameters in a shaft. The theoretical model is used to analyse the effects of surface climate on the deep environment in vertical shaft. The temperature of the airflow is affected by the seasonal climate, and the influence is weakened with the increase of the ventilation distance. The greater the relative humidity change in the vertical well, the smaller the variation of the airflow temperature value, and the decrease of the temperature is affected by the enthalpy. When the shaft deep humidity environment is certain, the greater the humidity, the greater the temperature change.

Abstract
To study the seismic response of rigid-subrigid pile composite foundation, shaking table test was conducted under sandy field condition. The experimental results show that the acceleration response strength of the pile top is greater than that of the pile bottom, and is smaller with the increase of buried depth; seismic wave types will have an impact on the acceleration amplification effect; from pile bottom to pile top, the peak value of Fourier spectrum increases gradually, and the frequency distribution of Fourier spectrum in frequency domain does not change. The frequency range of the peak value of Fourier spectrum under three kinds of seismic waves is different; with the peak acceleration of the input excitation increase, the strain peak of pile body changes more and more significantly along the length direction, and the strain peak of rigid pile appears abnormal, which is the weak part of seismic resistance.

Published: November 2019

Abstract
Based on national hazardous waste production data from 2008 to 2011, GM (1,1) grey model, unit industrial output value model and average annual growth rate model are used for prediction studies of which the prediction results was compared with the actual values of hazardous waste from 2012 to 2016. Under the selected background data, all the three widely-used models have large deviations. The model with the smallest deviation range is the annual growth rate model of which the prediction result is 1.25-2.05 times the actual value. The model with the second small deviation range is the unit output value model of which the prediction result is 1.36-3.63 times the actual value. GM (1,1) has the largest deviation range, of which the prediction result is 1.46-7.58 times the actual value. The causes of deviation are analyzed, and the results show that, due to the influence of different factors, the background data significantly rocketed in 2011 and 2016, resulting in the instability of the model prediction. Based on the application of the models, the applicability of different models is analyzed. It is suggested that the grey model should be preferred when there are a few data; and the easy-to-operate unit output value model and annual growth rate model shall be preferred when there are sufficient historical data. Meanwhile, the influence of industry and policy factors should be comprehensively considered to improve and optimize the prediction methods and parameters of the models, so as to provide reference for quantitative prediction of hazardous wastes.

Published: November 2019

Abstract
Based on the precipitation anomaly percentage index (Pa), the relative moisture index (MI), the standardized precipitation index (SPI), and the standardized precipitation evapotranspiration index (SPEI), the regional applicability was examined in Chongzuo over the period 1961to 2012. The results showed that: (1) The MI and Pa significantly underestimated severe drought and extreme drought at annul time scale. The monitoring result of annual SPEI and SPI was accurate and more close to the actual drought level. (2) The frequency range of different drought class is close to actual level for the SPI and SPEI at different time scale. The severe and extreme drought seldom occurred using Pa and MI monitoring results, the adaptability and reliability of MI were relatively lower in Chongzuo. (3) The annual MI and Pa showed smaller coverage with the severity of moderate and above drought than statistical results of SPI and SPEI in Chongzuo. (4) The SPI was found more sensitive to precipitation changes than the SPEI at 1-month scale in dry period. SPI and SPEI can be properly used for the monitoring as well.
