摘　　要：介绍了一种基于瑞典法和简化Bishop法分析抗滑桩加固边坡的极限平衡法.通过试算,可以确定边坡达到稳定要求时,需要桩提供的最小抗滑力及边坡潜在滑动面的位置,进而对抗滑桩的桩位进行优化.结合某闸室岸坡工程的算例表明,抗滑桩能有效提高边坡的稳定性;抗滑桩设在通过边坡潜在危险滑动面最低点时效果最好;设抗滑桩会改变边坡潜在危险滑动面位置.A limit-equilibrium method to study the stabilization of the river-side slope reinforced by stabilizing piles based on the Sweden and simplified Bishop theories is presented. With the trial method, the minimum anti-slide force provided by the piles and the location of the potential dangerous slip surface when the slope meets its stability demand can be determined, and the location of the pile can be optimized. Calculation results of an example of a gate′s slope show that the stabilizing pile can improve the stability of slopes, that setting the pile through the nadir of the potential dangerous slip surface can achieve the best effect, and that the location of the slip surface will be changed after setting stabilizing piles.
