Numerical simulation analysis of grouting masonry arch skeleton slope protection under train load
In the field of engineering,slurry masonry slope protection plays an important role in main-taining slope stability and preventing subgrade diseases such as erosion and slump.In this paper,the arch skeleton slope protection of grout masonry is taken as the research object,and three-di-mensional numerical simulation research method is adopted.MIDAS GTS software is used to con-duct three-dimensional modeling and mesh division,and FlAC3D is introduced to conduct numeri-cal simulation to analyze the displacement and acceleration response of arch skeleton slope protec-tion under train load.The results show that the displacement of slope top and slope foot is rela-tively maximum under train load,the displacement of upper arch skeleton is larger than that of lower arch skeleton,and the displacement of arch top is smaller than that of arch foot,which cor-responds to the development law of peak acceleration at each point.Therefore,the joint strength of the dangerous section should be controlled to prevent serious damage during the construction of the arched skeleton.
