摘要
衡重式挡土墙价格低廉,施工工艺简单,在实际工程中应用广泛。在市政道路拓宽改建过程中,由于受到施工现场已建道路管线以及场地空间有限等因素的影响,传统的衡重式挡土墙由于自身尺寸较大,与现有管线等冲突,无法满足设计要求。通过对衡重式挡土墙截面进行优化,降低了作用在墙身的土压力,进而减小了挡墙本身的尺寸,避免了现场地下管线的改迁,取得了良好的工程效益。
Due to the low price and simple construction technology,balance weight retaining wall was widely used in actual projects. During the process of municipal roads widening,affected by limited pipeline construction,area space and other factors,the balance weight retaining wall cannot able to meet the design requirements,because of their larger size and conflict with the existing pipeline. Through the section optimization of balance weight retaining wall,the soil pressure on retaining wall and wall size was reduced,the underground pipelines were not needed to removed,and the fruitful economic benefit was achieved.
