山区斜坡地段扶壁式挡墙倾斜加固的设计
摘要:以重庆某道路扶壁式挡墙倾斜事故为例,根据地质条件、土层岩土参数、挡墙设计参数及施工过程反馈的信息,对倾斜段挡墙进行复核,根据复核结果和挡墙的实际变形特征,分析了导致该段挡墙倾斜的可能原因,提出了采用预应力锚索对扶壁式挡墙整体稳定性加固的预防措施及地基注浆加固处理方案。
Abstract:This paper based on geological conditions, soil parameters, design parameters of counterfort retaining wall and feedback information of construction, analyzed the inclination accident of a road counterfort retaining wall located in Chongqing. According to the analysis of the result and deformation characteristics of counterfort retaining wall, analyzed the cause of counterfort retaining wall inclination. Finally, the foundation grouting reinforcement treatment and the precaution using prestressed anchorage to strengthen the stability of counterfort retaining wall is put forward.
