Authors: Chen Sinan , Liu Minghao , Liu Tianlin , Li Junyi 
Published: March 2021

Abstract
In the field of urban dynamic simulation, scholars are committed to exploring different models and methods to improve simulation accuracy. However, while the overall accuracy is improved, the imbalance of data results in relatively low accuracy of minority samples. How to improve the simulation accuracy of minority samples has become an important issue. This paper will solve this problem at the sampling level. The experiment is based on the GlobeLand30 land use data in the three phases of 2000, 2010, and 2020, and uses the ProWSyn (Proximity Weighted Synthetic Oversampling Technique) algorithm to balance the data. Train the model with land use data from 2000 to 2010, verify the model with data from 2010 to 2020, and finally simulate the future based on data from 2020. The results show that the ProWSyn-MLP-CA model constructed in this paper has improved the accuracy of minority samples to varying degrees. In the case of using the same neural network model, the KAPPA value of a small number of land types increased by an average of 30% after ProWSyn equalization.

Published: March 2021

Abstract
An innovative 3-Dimensional split resonant cavity (SRC) is introduced here as an enhancement of planar split-ring resonators (SRRs), which could overcome the strong dependence of SRRs on polarization. Numerical simulations demonstrate that multiple resonances, including electric dipole mode, magnetic dipole mode and interaction of both modes, can be excited by three different polarized incident electromagnetic (EM) waves. Fano resonance characterized by asymmetric transmission line shape due to interference of multiple modes is observed in the simulation.

Authors: Ping Zixin , Yue Mengchen , Wang Min , Wang Xiaohong 
Published: March 2021

Abstract
Numerical simulation of steam-flooding thermal heavy oil recovery is studied in this paper. Although the traditional full implicit scheme has high stability, it needs to calculate the huge sparse matrix and the computation cost is super expensive; so it cannot meet the needs of practical oil industry production. In this paper, sequential implicit scheme is applied to numerical computation of steam-flooding thermal heavy oil recovery. A quasi-one-dimension numerical example is tested to verify the validity and high efficiency of the proposed method against using traditional fully implicit scheme.

Authors: Chi Zecheng , Meng Zhaowei , Xie Linyu , Wang Wei , Zhang Weipeng 
Published: March 2021

Abstract
Based on the revised ALONSO model, combined with the ABAQUS software platform, this paper compiled the USDFLD subroutine and obtained the stress-strain curve and the axial strain-volume deformation by simulating the triaxial shear test of the unsaturated soil to control the suction and confining pressure. The curve verifies the accuracy and reliability of the algorithm. The research results show that: (1) When the suction is the same, the higher the confining pressure is, the higher the yield point of the soil sample is. According to the comparison between experiment and simulation, the modified Alonso model can reflect the nonlinearity of the stress-strain relationship of the reshaped unsaturated soil sample and its plastic flow characteristics; (2) Compared with saturated soil, unsaturated soil has a higher yield point as a result of the suction. And the larger the suction is, the higher the yield point is, which proves that the model can simulate the influence of unsaturated soil liquid relative to the solid phase.

Authors: Liu Guoshan , Yu Xiangkun , Zhu Ronghao , Dong Xu 
Published: March 2021

Abstract
To reveal influences of hydration heat in large-volume concrete, a large-volume concrete pile cap of a main bridge over a canal was taken as the engineering background. In the research, the finite element software, Madis civil, was used for simulation and analysis of hydration heat in the pile cap. Through finite element simulation, the temperature and stress fields were obtained and compared with the monitored data. Analysis results indicate that in the initial pouring stage of the pile cap, a large temperature difference occurs between the interior and surface of the pile cap; as the temperature difference enlarges, the temperature stress of the pile cap also increases correspondingly. The results of finite element analysis match well with the monitored data, which guarantees the construction quality in the field and verifies feasibility of the finite element software in simulation and analysis of hydration heat.

Authors: Zhang Yichao , Chen Xingyi , Zhou Jinghai , Huang Jian , Wang Qinghe 
Published: March 2021

Abstract
China and other developing countries are the largest consumers of concrete. The massive use of concrete consumes natural resources and produces construction waste, which leads to the shortage of landfill sites. Using recycled aggregate to prepare concrete cannot only meet the performance requirements of natural aggregate concrete, but also solve the problem of insufficient landfill site, which is in line with the essence of sustainable development. However, the interfacial transition zone is often the weak area of recycled concrete, which is the focus of current research. This paper summarizes the mechanical properties of recycled concrete ITZ, studies the existing problems, and looks forward to the future development trend.
