| 摘 要： | 目前抗滑桩己被广泛地应用于水库岸坡,如三峡库区内的岸坡的治理工程中。但是由于实际工程中抗滑桩大都是在枯水季节,低水位时施工成桩的,因此在库水从高水位到低水位变化的过程中,桩体无形中对坡体内地下水的流动形成了阻渗作用,这必定对治理工程的安全性评价产生影响。文中通过定量分析可以看出,目前不考虑桩体渗透性的计算方法将低估抗滑桩治理工程的安全性,使设计偏于保守,造成一定的浪费。同时,埋入式抗滑桩由于其桩顶部分是土体,相对的增大了抗滑桩所处断面处的渗透性,因此在保证治理工程安全性的前提下,采用埋入式抗滑桩将更为经济、合理。

| Abstract: | At present anti-slide piles have been widely used in slope of reservoir banks,such as the governanace of slopes in Three Gorges Reservoir area.Since most anti-slide piles are established during the dry season when the water level is low,the piles would hinder the flow of underground water when the water level changes,which causes influence on the safety evaluation of the governance.From the quantitative analysis given,the method ignoring the permeability of piles would underestimate the safety of governance... |
