Authors: Guang-ying Nie , Yu Xia , Qing-wen Zhang 
Published: February 2021

Abstract
The settlement and deformation of soft rock are the main problems hindering the construction of tunnel engineering. The use of soft rock and its residual soil has become the focus of engineering development at home and abroad. Sericite schist is an extremely soft rock, and most of the sericite schist residual soil in nature is in an unsaturated state. The Baishitou Tunnel of Dali-Lincang Railway is located in Yun County, Lincang City, Yunnan Province. The surrounding rock in the tunnel is mainly soft rock, such as sericite schist and carbonaceous schist. Due to the action of the earthquake, the rock mass is easily broken and its strength is low, making construction extremely difficult. Strongly weathered sericite schist has the characteristics of soft rock, easy to weather, and the rock mass is relatively easy to break. Its residual soil has similar properties to its parent rock and is often encountered in actual engineering. The research on unsaturated strongly weathered sericite schist and its residual soil has become the focus of research by scholars at home and abroad. The engineering properties of unsaturated soils have become one of the main research directions of soil mechanics.

Published: February 2021

Abstract
Groundwater plays an important role for agricultural irrigation in the Guanzhong Basin. In order to investigate its spatial distribution characteristics of groundwater suitability for irrigation in the central-western Guanzhong Basin, total 97 groundwater samples were collected and analysed. Four indicators, including sodium percentage (Na%), residual sodium carbonate (RSC), magnesium hazard (MH), and potential salinity (PS), were selected to evaluate the groundwater for irrigation use. The results show that the groundwater in the southern and western areas is more suitable for irrigation than that in the northern and central areas of the basin. Besides, the consistent evaluation results are obtained based on these four indicators, which indicates that they are applicable for the assessment of groundwater irrigation use in study area. Furthermore, the findings of this study would provide guidance for spatial management decision of irrigation groundwater in the central-western Guanzhong Basin.

Research on Carbon Emissions Reduction of Iron and Steel Remanufacturing Industry Supply Chain
Authors: Xiao Liming Zhang Gang , Chen Xuewu , Yang Wei 
Published: February 2021

Abstract
The steel industry occupies an important position in China's economic development, but it also consumes a lot of energy and produces CO2. Iron and steel remanufacturing can recycle scrap iron as raw materials for crude steel smelting and reduce energy consumption. However, different raw materials in the supply chain will result in different steel plants’ choice of supplier, purchase volume, and production volume. These choices will affect the economic cost and carbon emissions of the entire system. This paper establishes a model to simulate the economic cost and carbon emissions of the supply chain system. Under various constraints, the carbon emissions are set at 95% and 90% of the previous year's carbon emissions as constraints to solve the system’s impact on suppliers selection and processing distribution of steel plants. The results show that as carbon emission constraints become more stringent, steel plants will choose suppliers with better quality raw materials, and processing production will shift to steel plants with lower carbon emission factors. It is worth noting that with the strict carbon emission restrictions, at 90%, the economic cost will rise rapidly, so too strict carbon emission restrictions should be carefully considered.

Abstract
In order to sufficiently study the effects of stirring speed and temperature on the membrane flux, the flux recovery rate (FRR) and model parameters (k1, k2, k3
and Ri
) of the PAN membrane (200kDa) fouled by yeast suspension, a series of rinsing experiments were carried out. Meanwhile, the instantaneous membrane flux was predicted by the rinsing model and corresponding regression equation of model parameters was obtained. The result indicated that the model shows a good agreement (R
2>0.9700) and the temperature has a more significant effect on FRR and model parameters (k1, k2, k3
and Ri
). FRR increased from 58.40% to 99.41% when the temperature increase from 25°C to 55°C (the rate constant of dissolution increased from 0.00371 m−1 to 0.00531 m−1) while it only increased from 55.67% to 67.50% when the stirring speed increases from 200 rpm to 800 rpm (the rate constant of dissolution increased from 0.00366 m−1 to 0.00456 m−1). In addition, the rinsing condition can be optimized by the combination of the prediction model of flux (equation (1)) and the regression equation (equation (2)) to obtain the optimal cleaning condition.

Research on Reliability Evaluation Method of Sanitation Vehicles under Small Sample Data
Authors: He YuLong 
Published: February 2021

Abstract
Aiming at the problem of insufficient failure data of sanitation vehicles, a data expansion model based on gray neural network is proposed. First, the gray model is used to predict the error sequence between the true value and the predicted value; input the error sequence into the neural network, and calculate the error prediction sequence by adjusting parameters such as neurons and weights; the predicted error sequence is multiplied by the weight coefficient and subtracted from the prediction result of the gray model to obtain the final prediction result. The results show that the combined forecasting model is more accurate. This method enlarges the number of fault data samples while maintaining the original data distribution law to determine the reliability distribution model.

Analysis and Peak Value Prediction of Rainfall Component Factors Influencing Seepage Flow for Homogeneous Earth Dams
Authors: He Lu , Wang Shijun , Gu Yanchang , Pang Qiong , Wu Yunxing 
Published: February 2021

AbstractThe rainfall component of seepage flow is an important indicator for monitoring earth dam safety. Compared with previous practice of only analyzing rainfall, this paper divides the analysis dimensions into three categories according to the seepage process in the process of rainfall: the saturation permeability coefficient of the soil receiving the rainfall, the rainfall intensity and rainfall duration. This paper conducted FE simulation according to the principle of unsaturated seepage flow, and it is concluded that: the influence of different rainfall intensity on seepage flow is roughly linear and can be expressed by a first power factor; the influence of different saturation permeability coefficient and rainfall duration on seepage flow is obviously nonlinear, and should be expressed by multiple powers. Based on the above law, the model expression of peak seepage flow prediction was established, and both the fitting effect and prediction accuracy were good. The results show that the law of influence factors has been summarized correctly, and the research result can provide effective theoretical support for the seepage flow monitoring and early warning and safety monitoring for homogeneous earth dams.
