| 摘 要： | 通过对临桂县4座水库大坝坝身、坝基进行钻探、取样与现场试验,进行相关的室内试验以及现场安全检查,采用二维渗流有限元计算方法、简化Bishop法以及瑞典圆弧法等定量分析方法.利用ANSYS和MATLAB计算软件,求解渗流水头并计算渗漏流量,对4座水库大坝的渗漏安全性进行对比分析与评价,4座大坝坝体填土渗透系数值在2×10-4～5×10-4cm/s之间远大于安全值1×10-4cm/s,压实度在90.4%～94.4%之间,远低于安全要求的95%～97%,坝体的最大渗透比降为低于或基本处于允许坡降值.存在比较严重的渗漏安全隐患,并结合野外与室内试验可评定4座水库大坝均为三类坝,需进行坝体、涵管、溢洪道等进行综合加固处理.

| Abstract: | In order to study seepage safety of the four dams,efforts have been made,including not only drilling and sampling the dam body and foundation in-situ,and testing the physical and mechanical indexes of filling soil indoor,but also employing quantitative calculation methods,for example two-dimensional finite element seepage analysis and simplified Bishop method and the Sweden slip circular method.Adopting software ANSYS and MATLAB,seepage head and seepage volume have been calculated.When analyzing synthetical... |
