Abstract Research purposes ： As the accelerating pace of construction of domestic highway, railway and civil aviation, there has been many great propulsion engineering landslides in the high intensity seismic region of western China, which always had characteristics of multilayer and multilevel significantly. Double - row anti - slide pile was the effective measures to control the large landslide. Combined with the typical engineering examples such as Yushu airport road landslide in Qinghai Province and Panzhihua airport landslide in Sichuan Province, double - row anti - slide pile is studied how to govern the large sliding surface landslide by the large - scale shaking table model test in X , Z and XZ direction three kinds of load conditions , the characteristics of dynamic response of double - row anti - slide pile and deformation & destruction of landslide were analyzed.
Research conclusions:(1) Double - row pile tests showed that the effect of governance with double - row pile on large - scale multilayer sliding surfaces is obvious , which reflected very well the design concept of 11 no collapsing with strong earthquake" . (2) Durng the tral , the overall defomation mode of slope is mainly tensile - shear failure , the platform at the back of slope is given prcTy to seismic subsidence，the sliding body is layered and forward，and the interface effect is obvious , sliding surface gradually developed to deep , clamping effect was significant on both sides of the model box. (3 ) Test data analysis showed that thrst allocation proportion of two rows anti - slide piles was not the back row piles bore most of the landslide thrnst (mainly came from landslide thrnst of the deep sliding body) , and landslide thrust ratio was smaller in the front row piles. (4 ) The study has very important theoretical and practical significance for dynamic performance analysis of the double - row pile.
