| 摘 要： | 以某小型水库为研究对象,通过采用北京理正公司岩土系列软件的渗流有限元分析法对坝体进行渗流分析,确定了大坝在各种工况下的单宽渗流量、浸润线出逸点位置及对应的渗透比降,并采用瑞典圆弧法对坝体进行坝坡稳定分析,计算大坝上下游坝坡抗滑稳定安全系数,判断其是否满足规范要求,其成果可为同类工程的大坝除险加固设计提供参考依据。

| Abstract: | In this paper, we use a small reservoir as the research object. Through the adoption of the software which has been founded by the Bei- jing Lizheng geotechnical company. We use the seepage finite element analysis method to make a study on the dam seepage analysis. So we can determine the per unit width seepage flow, the escape point of the saturation line, the corresponding seepage gradient. The use the Sweden arc method to make the dam slope stability analysis of the dam, then calculate the dam upstream and downstream dam slope stability safety factor a- gainst sliding, make a conclusion whether it meet the specification requirement. Its-results can provide reference for design of the same kind of engineering dam and consolidate the basis. |
