不同参数条件下抗滑桩的力学性状分析

Analysis of Mechanical Properties of Anti-slide Pile under Different Parameters

为了研究不同参数抗滑桩对边坡加固效果的影响,选取不同截面形状抗滑桩分别在相同截面积、抗弯刚度、不同桩间距和相同抗弯刚度、不同截面面积两种情况进行数值模拟,运用强度折减法对桩-边坡体系进行计算,分析安全系数随抗滑桩截面形状、桩间距、截面面积的变化趋势,发现抗滑桩截面边数目与边坡加固效果之间的必然联系,揭示不同截面形状、截面面积和桩间距对抗滑桩内力、边坡位移的影响规律。

In order to study the influence of different parameters of anti-slide pile on the slope reinforcement effect,the paper selectes anti-slide piles with different section shapes for numerical simulation under the two conditions of the same sectional area,bending stiffness,different pile spacing,same bending stiffness and different section area.By using the strength reduction method to calculate the pile-soil unit,the paper analyzes the variation trend of safety coefficient with section shape,pile spacing and section area of anti-slide pile,discovers the inevitable relation between the number of sides of anti-slide pile section and the reinforce effect of slope and reveals.The influence law of different section shapes,section areas and pile spacing on internal force and slope displacement of anti-slide piles.
