中峰水库心墙填筑压实度超百分析

黏土心墙碾压填筑压实度作为土石坝填筑的主要技术控制指标之一,是保证土坝防渗体施工质量,提高防渗体的密实度和均匀性,防止土石坝心墙坝体不均匀沉陷变形和渗漏的关键。本文以中峰水库为例,对工程建设中出现的土石坝心墙坝体压实度超过100%的问题进行分析。

Analysis of Core-wall Filling Compaction Degree Over 100 % Reservoir in Zhongfeng

As one of key technical control indicators in embankment dam filling, clay core-wall rolling and filling compaction degree is critical for ensuring construction quality of soil dam anti-seepage body, improving density and uniformity of anti-seepage body, and preventing embankment darn core wall dam uneven depression, deformation and seepage. Zhongfeng Reservoir is adopted as an example in the paper. The issue of embankment dam core-wall dam compaction degree in the project construction over 100% is analyzed.
