摘　　要：鉴于大幺姑滑坡土体特征、地形地貌及年降雨量等因素有可能使滑坡体复活的问题,使用ABAQUS对大幺姑滑坡进行模拟,通过不同的抗滑桩排列形式得到合理的抗滑桩组合,采用强度折减法得到了不同抗滑桩的强度安全系数,可知在两排桩布置下安全系数为2.25时最为合理,从而为了解大幺姑地区的边坡滑移规律及其治理提供依据。Due to the imperfect of landslide control, and other factors, such as geomorphological and geotechnical characteristics, topography and geomorphology and annual rainfall, Dayaogu landslide has the risk of sliding. ABQUS software is used to simulate Dayaogu landslide. And then the rational combination of anti slide pile is obtained by arraying different anti slide pile. Finally, strength reduction method is applied to calculate the strength safety factor of anti slide pile. The simulation results show that the rational combination was two anti slide piles and the safety factor was 2.25. Thus, it provides scientific basis for finding out the regularity of Dayaogu landslide and its regulation project.
