边坡支护受力性能及承载力分析

Analysis of Stress Performance and Bearing Capacity of Side Slope Support

为了研究边坡路基支护的受力,开展了边坡路基支护的受力性能和承载力分析。提出了在边坡段影响路基性能的几个影响因素,并利用试块压重平台反力装置,对某工程路基上的水泥搅拌桩进行了单桩竖向抗压静载试验,从而检测了桩的单桩竖向抗压承载力是否满足设计要求,并研究了随着竖向荷载的增加,桩基的沉降量和累计的沉降量,不同桩基的最大沉降量和最大回弹量,并研究了桩基的回弹率曲线。

In order to study the stress of slope subgrade support, the stress performance and bearing capacity of slope subgrade support are analyzed. Several influencing factors on subgrade performance in slope section are proposed, and use the counter force device of the test block weight platform, the vertical compressive static load test of single cement mixing pile on the subgrade of a project is carried out, so as to check whether the vertical compressive bearing capacity of a single pile meets the design requirements, and with the increase of vertical load, settlement and accumulated settlement of pile foundation, maximum settlement and maximum rebound of different pile foundations, and the rebound rate curve of pile foundation are studied.
