摘要
衡重式挡土墙具有良好的结构自稳性,能够减少开挖和回填量,在山区公路改扩建工程中应用较多。但是,受山区地形限制,衡重式挡土墙地基承力不足的情况也较为常见。该文主要分析在挡土墙基坑地基承载力以及基坑尺寸不足情况下衡重式挡土墙的施工方法:增设钢筋混凝土扩大基础及基础斜拉锚杆,并在该基础上修建挡土墙。经过长时间的监测,发现扩大的基础以及挡土墙墙身无裂缝,且几乎无沉降位移,能够有效保证挡墙的施工安全以及后期的安全使用,可为同类工程施工提供参考。
The balance-weight retaining wall has remarkable structural self-stability,so it can reduce the amount of excavation and backfilling,and it is widely used in mountainous road reconstruction and expansion projects.However,limited by the mountainous terrain,the insufficient foundation bearing capacity of the balance-weight retaining wall is also common.This paper focuses on the construction method of the balance-weight retaining wall with insufficient foundation bearing capacity and the foundation pit size:adding reinforced concrete to expand the foundation and oblique foundation anchor rods,and building retaining walls on the foundation.After a long period of monitoring,it was found that the expanded foundation and the retaining wall had no cracks,with little settlement displacement.It can effectively ensure the construction safety of the retaining wall and the later safe use,which can provide a reference for the construction of similar projects.
