小型水库除险加固地质勘察实践——以那卧水库为例

Geological Investigation Practice of Disaster Elimination and Reinforcement of Small Reservoirs:A Case Study of Nawo Reservoir

那卧水库受病害影响不能在正常水位运行,常年处于低水位运行状态,水库防洪、灌溉功能无法正常发挥,不利于下游沿线村庄防洪和农田灌溉。为恢复水库防洪、灌溉功能,需对那卧水库进行除险加固。通过对那卧水库除险加固工程开展工程地质勘察,查明水库病害原因,为水库除险加固工程设计提供地质建议与依据。

Affected by the disease,the Naghu Reservoir cannot operate at normal water level,it operateds at low water level all year round.The flood control and irrigation functions of the reservoir is not functioning properly,which is not conducive to the flood control and farmland irrigation of villages along the downstream.In order to restore the flood control and irrigation function of the reservoir,it is necessary to eliminate the disaster and reinforce the reservoir.The geological investigation work of the disaster elimination and reinforcement engineering of Nawu Reservoir is carried out,so as to find out the causes of the reservoir disaster and provide geological suggestions and basis for the design of the reinforcement engineering.
