摘要
泄滩滑坡坡体在剖面上从上到下共分为坡积物、滑坡堆积物、滑带、滑坡影响带以及基岩五层 ,从水力学特性来看为三层透水性较强的岩层 (坡积物、滑坡堆积物和滑坡影响带 )和两层透水性较弱的岩层 (滑带和基岩 )构成的互层状结构。以此为基础 ,进行了三峡库区蓄水至Δ 1 35m和Δ 1 75m时泄滩滑坡的渗流场分析 ,得出滑坡体内水头分布和滑带承受的浮托力分布。可以看出 。
The Xietan slide can be divided into five layers as:slope wash,deposit,sliding zone,effecting zone and bed rock,thus forming the inter layered structure with three permeable layers(wash,deposit,and effecting zone)and two relatively impermeable layers(sliding zone and bed rock).The seepage fields in the Xietan slide are analyzed when the storage water level reaches Δ135m and Δ175m,the hydraulic head distribtuions in the slide and the uplift pressure distributions along the bottom of the sliding zone are also obtained and analyzed.It can be concluded that the inter layered structure is not benefit to the stability of the Xietan slide.
