The numerical simulation analysis on safety stability in underground space of urban track transportation system Hongye Chen1, a, Jingfei Zhang2*,b* , Huizhong Ma3, c, Jinying Ma4,d 1,2*,3Department of Engineering Mechanics, Zhengzhou University, Zhengzhou 450001, Henan Province, China 4Henan Zhongzi certified safety engineer Co.
The applied research indicates that the numerical simulation analysis can express the risk characteristics and rules well during engineering construction and after construction, and further avoid potential hazards or accidents’ occurrence, which has important meanings for ensuring the safety of engineering projects during the whole process.
Based on one underground station of zhengzhou city as an example, it uses Three Dimensional Fast Lagrangian Continua, combines the related software technology supported by the Traffic and Structural Engineering Technology Research Institute of Zhengzhou University , carries on simulation analysis on aspects of surrounding soil’s displacement and stress during excavation stages,and emphatically analyzes the stress-strain rule of main structure during engineering construction and after construction process.The applied research can provide technical basis and reference for stability engineering design, safety construction and safety operation in underground space of urban track transportation system.
It is used widely in civil engineering, communications, water conservancy, oil and mining engineering, etc.[10-12].

Experimental Research on The Confinement Effect for the Composite Concrete-Filled Square Steel Tubular Short Columns Bin LI a, Chunyan Gao b The college of architecture and civil engineering, Inner Mongolia University of science and technology, Baotou, 014010, China aemail:btlibin@189.cn, bemail:gao-197844@163.com Keywords: Composite Column; Axial Compression; Bearing Capacity; Confinement Coefficient; Ductility Abstract.
So it is suggested that in engineering design the confinement coefficient ξ of composite columns should be greater than 1. 3.
The bearing capacity formulas recommended in this paper are in good agreement with the measured results, which can be applied to the engineering practice.
