某水库坝前变形边坡勘察与稳定性分析

Analysis on Survey and Stability of Deformed Slope Before the Dam of a Reservoir

某水库拟选定坝址在前期勘察过程中发现坝轴线处有一大型变形边坡,通过多种勘察方法,确定了变形体范围、性质,并在各种工况下对其进行稳定性分析,及时调整设计方案,避免了在施工时或水库运行时发生重大地质灾害的可能。

A place, located at Xianju County of Zhejiang Province, has been chosen as the proposed dam site of reservoir, during the process of pre-phase investigation, a large-scale deformed slope is found on the axial line of the dam. By several surveying methods, the range and features of the deformed body are determined, and its stability is analyzed under each construction condition, therefore, the design scheme is adjusted in time to avoid the serious geological disasters occurred during construction or operation of the reservoir.
