某边坡工程的加固措施研究

Researches on Reinforcement Measures of a Slope project

结合工程实例,阐述了某边坡初次加固失败,进而采用二次加固措施。二次加固要考虑初次加固排桩的有利作用,最终确定在已有支护桩前加打两排冲(钻)孔灌注桩,用冠梁、连梁板、竖向斜撑梁以及桩间腰梁将两次支护桩连成一个整体,形成刚度较大的加固体系。该加固体系在完工后的监测中,变形量较小,满足安全要求。

Based on an engineering project,this paper stated the failure of the initial reinforcement on a slope,and the second reinforcement measures adopted. The effect of initial reinforcement of the row piles should be considered during the second reinforcement. Therefore,it was determined that two rows of impact-cone concrete piles（ or bored piles） Were added before the existing retaining piles,and that crown beam,coupling beam board,vertical brace beam and waist beam between piles were utilized to connect the two support piles to form the reinforcing system with a greater stiffness. In the post-completion of the reinforcement system,the deformation was small from the monitoring results. It can meet the safety requirements.
