超高扶壁式挡土墙的稳定性检测鉴定实例分析

Case Analysis about Stability Detection and Identification of Superhigh Counterfort Retaining Wall

为了对已建的、存在安全隐患的超高挡土墙的检测鉴定方法进行研究,选取某超高扶壁式挡土墙为工程实例进行分析.首先根据相关施工资料及现场勘测情况提出稳定性与安全性鉴定方案,并据此进行检测鉴定工作;然后,选取典型截面进行计算分析,计算结果能很好的反映实际施工及使用情况.最后,提出挡土墙的稳定性与安全性结论,并提出相应的加固处理措施,以期为该类工程的质量安全举措提供一定的借鉴作用.

In order to research the stability detection and identification method for the superhigh counterfort retaining wall which exists and has some security threat, this paper selects one real superhigh counterfort re- taining wall as the engineering example for analysis. Firstly, according to the relevant construction site in- vestigation information, a security and stability assessment plan is presented and the detection and identifi- cation work goes on with this plan. Then, a typical cross-section is selected for calculation and analysis, and the calculation results can reflect actual construction and usage very well. Finally, the conclusion about the security and stability of the retaining wall and the appropriate reinforcement measures are proposed, which can be used for a reference of the similar engineering.
