【摘要】 一般认为库水位骤降时对土坝安全的影响较大,而不太注意库水位变幅很大时,渗透力对土坝安全的影响。本文通过对岳城水库主坝浅层滑坡原因的分析,说明库水位大幅度消落导致的渗透力对土坝安全的影响是很大的,应该引起足够的重视。并从水库运行的角度,说明了均质土坝不宜过高。更多还原

【Abstract】 It is commonly considered to be harmful to the safety of an earth fill dam that the reservoir water level declines rapidly, but the influence of the percolation force on the safety is often neglected when the reservoir water level declines heavy. Through analyzing the main dam of Yuecheng Reservoir slid surface, the influence of the percolation force on the safety of an earth fill dam is so heavy, and it should be regarded highly. Homogeneous high earth fill dam is not suitable.更多还原
