摘要
结合中洞水库的现场地质勘探及室内试验资料,采用有限元方法研究分析了大坝的渗流稳定问题,分析可知大坝存在着浸润线相对较高、单宽流量过大、坝基及下游坡脚处渗透坡降过大等问题。结果表明:大坝的渗流形态不安全,水库存在着安全隐患。
Combination with geological exploration and laboratory test of Zhongdong Reservoir dam, the seepage flow of the dam is calculated by using finite element method as well as the monitoring data of the dam is analyzed. The analysis shows that the relatively high saturation line and single width flow is too large of the dam. Permeability gradient is also large of downstream of the dam foundation and the foot of the slope department. So the seepage is unsafe, the existence of security risks reservoir.
