崂山龙潭水库坝址渗透试验分析

文章针对崂山龙潭水库坝址区采取工程地质钻探、压水试验等手段,查明了坝址区的工程水文地质特征,经过对不同位置3个钻孔12个试验段的压水试验结果分析得出,坝基渗透性等级属微透水—弱透水。

Analysis on penetration test of dam site of Longtan reservoir in Laoshan

The permeability of the reservoir dam site directly affects the stability of the dam site and the leakage of the reservoir. It has always been a major concern. In this paper, engineering geological drilling and water pressure test were taken for the dam site area of Longshan Reservoir in Lushan, and the hydrogeological characteristics of the project in the dam site area were ascertained. Through the analysis of the water pressure test results of 12 test sections of three boreholes in different locations of the dam site, it is concluded that the permeability grade of the dam foundation of Longtan Reservoir is micro-permeable to weakly permeable, which provides a date basis for the anti-seepage design of the dam site of Longtan reservoir improvement project. It can also be used as a reference for seepage prevention of reservoir dam sites at similar engineering sites.
