| 摘 要： | 通过勘察拟建乌江大桥桥址区的地层产状、岩性、构造节理,对桥位中心附近的一个巨大的潜在蠕动山体进行了稳定性分析,认为该山体整体稳定,但地下水浸润后形成的润滑带,新构造运动导致的地壳强烈抬升以及贯通裂隙的切割都会使潜在蠕动山体失稳,从而改变桥墩的分布压力,并造成山体局部崩塌、落石,对拟建大桥桥位构成一定的潜在危害。

| Abstract: | According to the field survey of stratum attitude,lithology,tectonic joints at the proposed site area of Wujiang River Bridge,the stability of a giant potential creeping rock mass is analyzed.The result shows that the rock mass is stable as a whole under nature condition.But lubricating zone formed by infiltrating of groundwater,the crustal strongly uplift by the new tectonic movement and cutting cracks all would cause instability of the potential creeping rock mass,which could change the pressure distribution of the bridge piers and causes by locally collapsing and falling at proposed location of Wujiang River Bridge. |
