提高既有线路堑重力式挡土墙稳定性的几种实用方法

Practical Approaches to Improve Stability of Gravity Retaining Wall in Cutting Section of Existing Line

分析了既有线路堑地段重力式挡土墙稳定性降低的原因,介绍了刷坡减载提高抗滑稳定系数的原理,并根据病害检测结果,提出了提高稳定系数的几种实用方法以及墙背浸水条件下的排水加固补强措施,对既有线路堑地段重力式挡土墙的维护具有现实意义。

This paper analyzed why stability of gravity retaining wall in cutting section ot exlstmg tree was reduced, and introduced the principle how slop cutting and load shedding may improve the stability coefficient. Then, according to defect inspection, some practical approaches to improve the coefficient were proposed, with the drainage and reinforcement measures on condition of wall back under water, which have practical significance to maintenance of such retaining wall.
