抗滑桩的土拱效应研究

Study on the soil arching effect of anti slide pile

针对滑坡治理工程中抗滑桩与土体的相互作用引起的土拱效应对抗滑桩布桩的影响,结合已有的研究成果,对滑坡确定潜在滑动面,计算出滑坡推力,并基于PLAXIS有限元软件对潜在滑坡进行了分析计算,最终确定了此次滑坡工程中抗滑桩设计的最佳桩间距,为实际工程中抗滑桩的设计提供了依据。

Be aimed at the effect of the arrangement of anti slide pile of the interaction between pile and soil caused by landslide treatment engi-neering soil arching effect,and combined with the results of previous studies,to determine the potential sliding surface of landslide,and to calcu-late the landslide thrust,then use the finite element software PLAXIS to analyze the potential landslide,and ultimately determined the optimal pile spacing about pile design of landslide engineering,and provides a basis for the design of anti slide pile in practical engineering.
