某公路衡重式高挡墙病害分析与处治

本文对某衡重式挡土墙典型病害情况进行了分析和讨论,找出了病害产生的原因,通过数值模拟计算分析了此类挡墙的变形及受力特征,发现墙体范围内将有两处出现拉应力区,易发生开裂破坏,得出了此类挡墙顶部以上填土高度不宜大于6.0m,最高不应大于8.0m的结论。在深入分析和计算的基础上,制定了有针对性的加固处治方案,本文所得到的结论对此类挡土墙的处治有一定的借鉴意义。

Damage analysis of balance-weight high retaining wall of certain highway and the treatment

The typical disease of certain balance weight retaining wall is analyzed and discussed, and the cause of the disease is found. Through the numerical simulation analysis on this kind of retaining wall deformation and stress characteristics, it is found there will be two tensile stress zones where the cracking failure is easy to occur. It is confirmed that the fill height above the top of the kind of retaining wall should not be larger than 6.0m, the maximum height should not be greater than 8.0m. Based on the deep analysis and calculation, the reinforcement treatment scheme targeted is presented. The conclusions in this paper on the retaining wall treatment are of the guiding significance for the similar retaining walls.
