沟后水库溃坝原因分析及经验教训

Cause Analysis of DamFailure of Gouhou Reservoir

通过在现场坝体布点开挖探坑，对坝体填筑质量、干密度、坝体分区等溃坝后的现状进行测试研究，并对沟后水库建坝前后的设计、施工、质量检测和溃坝后洪水计算资料进行整理分析，总结了沟后坝溃坝原因及经验教训。

The paper analyzes the causes of the damfailure of Gouhou reservior through the data collected by means of routing process and quality detecting,before and after the construction of the dam as well as the test study on the status after the failure of the dam.The acceptance rate,the dry density,the quality of the dam are studied as well by trial pits and spotting on the site.
