水电站边坡滑面强度参数反演

Inversion of a Hydropower Station Slope Slip Surface Strength Parameters

该边坡为大坝建设区安全、稳定性要求最高的边坡,其整体稳定性直接影响到坝段的成立,对坝址的选择具有决定性的影响。对该区域的地质、水文资料的观测推测该边坡整体上不稳定,在现有资料的分析基础上,判断该边坡可能的破坏模式为覆盖层内部的滑动和沿基覆界面的深层滑动。基于现场量测结果和边坡安全系数的计算方法,对边坡的土体力学强度参数进行安全参数反演分析。

The accumulation of the dam construction area accumulation security, stability requires the highest accumulation, which directly affect the overall stability of the dam of the establishment, has a decisive influence on the choice of the dam site. According to the geological, hydrological observation data for the region as a whole speculate on the slope instability, based on the analysis of available information on the body lo determine the accumulation of possible failure modes for overlay sliding inside and along the base of the deep cover interface slide. Based on field measurements and slope safety coefficient calculation method, safety parameter inversion analysis was conducted on strength pa- rameters of slope soil mechanics.
