既有重力式挡墙的失稳原因及加固措施分析

Analysis of instability causes and reinforcement measures of existing gravity retaining wall

重力式挡墙在使用过程中容易出现开裂、倾斜等问题,为了使挡墙能够控制边坡变形,往往需要对既有挡墙进行加固。本文以福建地区某既有重力式挡墙为例,采用工程经验法和数值模拟法对挡墙出现裂缝的原因进行分析,并针对挡墙具体情况设计加固方案,通过数值模拟计算和分析现场监测数据,进一步验证挡墙加固效果,为类似挡墙加固设计提供参考。

The retaining wall is easy to crack and tilt during use.In order to control the deformation of slope,the existing retaining wall is often needed to be reinforced.Taking an existing gravity retaining wall in Fujian as an example,this paper analyzes the causes of cracks in the retaining wall by using engineering experience method and numerical simulation method,and designs a reinforcement scheme according to the specific situation of the retaining wall.Through numerical simulation calculation and analysis of field monitoring data,the reinforcement effect of the retaining wall is further verified,providing reference for the reinforcement design of similar retaining walls.
