Abstract:
In order to deeply understand the recent advances in closely-attached intersecting underground structures, the characteristic engineering, the most widely used construction method, the law of deformation and internal force and earthquake resistance were summarized respectively based on the summary of recent engineering and literature research. The advantages and disadvantages of each method were discussed and compared. The fact that further research topics mainly on the applicability of the different construction methods, the main factors that influence the method in construction, the steps of deformation distribution and force transformation in construction, the settlement mechanism and seismic analysis are still needed, was recognized, and suggestions for guidance for effective engineering were provided.
