沟后水库溃坝机理现场复核试验研究

Field stratification checking test on Gouhou collapsed dam

沟后水库修复工程是在保留部分原坝残留体的基础上进行的,就残留体开挖,对不同高程、段开挖形成的纵横断面进行坝料物理性状的检查、试验,尤其对3265 0m高程以上开挖体中有无形成渗漏通道的检查,以及对防浪墙底板、混凝土面板与填筑坝体间脱离状态的检查测量结果进行了分析,为进一步探讨溃坝原因提供了依据。这对今后该类型坝的设计、施工与管理必定是有益的。

The repairing project on Gouhou reservoir was held on the remains of the original dam body. The analysis on checking, testing of dam material physical properties on different height, cross section dig on the remains, especially at the dam height above 3265.0 m are made. The seepage and the bottom slab of waveprotection wall, the board between the gravelfillers respectively were checked and analyzed, which will be useful to the design, construction and management of similar dam in the future.
