摘　　要：由于前期勘察的疏漏,导致陶家沟特大桥3#墩台12根基桩分置于断层上下两盘,而暴雨引发的滑坡又使得该墩台位于断层上盘的部分基桩裸露,同时在墩台的南西侧由于滑移牵引效果使Ⅱ号滑坡体复活,对3#墩台的稳定性构成极大威胁。因此有必要对Ⅱ号滑坡体进行专题性勘察,评价其稳定性,为滑坡治理提供依据。due to the neglect of preliminary investigation, abutment 3 of Taojiagou super long bridge is set at an extremely unreasonable location. Storms led to landslide and got part of the abutment exposed outside while the movement and hauling effect of the southwest side of the abutment make the landslide Ⅱ reactive and subsequently it causes great threat to the stability of abutment 3. Therefore, it is necessary to conduct specific investigation on landslide Ⅱ, assess its stability and provide evidence for its treatment.

关 键 词：Ⅱ号滑坡体 3#墩台 稳定性
