摘要
结合前期勘察成果,查明筑坝土的土体材料、物理力学性质指标、渗透指标及击实指标,分析评价筑坝土的质量及坝基岩土层的稳定性及坝基砂土的地震液化问题,查明坝基渗漏段的渗漏原因,确定渗漏土层,为工程施工提供参考。
Previous survey results are combined for finding out dam soil material,physical and mechanical property indexes,penetration index and compaction index.Quality of dam soil,stability of dam foundation soil and rock layer and earthquake liquefaction problem of sand and soil on the dam foundation are analyzed.Seepage reasons in the dam foundation seepage section are investigated,leakage soil layer is determined,thereby providing reference for engineering construction.
