| 摘 要： | 安定桥滑坡位于四川省木里县博查公路约72公里处。滑坡地层为第四系松散堆积物,松散堆积物中有地下水存在。坡体内有软弱夹层。属于古滑坡体上的部分复活。坡体的滑动是由于古滑坡体内软弱夹层在上部岩体的自重应力及外部因素的综合作用下,产生的蠕动变形。两座拱桥的变形破裂是安定桥滑坡滑动变形所致。对两座拱桥实行加固和修复,有利于坡体的稳定和地方交通安全。

| Abstract: | The An-Ding bridge landslide is at 72 km of the Bocha highway. Muli county,Sichuan province. The stratum of the landslide is the loose deposit of the Quaternary,and there are groundwater in the deposit. The slope has a weak double layer,which belongs to a section of an old landslide, the movement of the slope was a creep deformation of the weak double layer caused by the gravitational stress and other factors.the deformation and burst of the two arched bridge is caused by the moves of the landslide. It is advantage to stable slope and safety traffic to reinforce and rebuild the two bridges. |
