珊溪水库增设大坝量水堰工程措施研究

Study on adding flow measuring weir for Shanxi reservoir

珊溪水库工程建成于2000年,在大坝坝基及面板周边缝内埋设了渗压计,可通过渗压观测资料分析、判断坝基的渗漏情况,但随着水库的运行,多数渗压计已损坏、失效,无法提供正常的量测数据。为确保大坝安全,需恢复大坝的渗流观测设施,因此笔者对设置坝后量水堰的工程措施进行了研究。

The Shanxi reservoir was completed in 2000. The osmometers were buried in the dam founda-tion and the perimeter joints of the face slab. The leakage of dam foundation can be determined by analy-sis of the observation data. After years of operation, most of the osmometers have been damaged orfailed, and cauld not provide measurement data. To ensure dam safety, the seepage observation facilitiesof the dam need to be restored. In this paper, the author studies the engineering measures to add flowmeasuring weir behind dam.
