摘要
为了有效解决重力式挡土墙裂缝问题,通过对某基坑开挖工程项目的研究,分析重力式挡土墙裂缝发生情况,总结发生裂缝原因,并提出具体有效解决方案,结果表明采用挡土墙卸载加上锚喷面层和钢管支护的方法能够阻止裂缝发展。可见,削坡、放坡、锚喷面层、钢管支撑加固方案可以保证重力式挡土墙安全。
In order to effectively solve the problem of cracks in the gravity retaining wall,through the study of a foundation pit excavation project,the occurrence of cracks in the gravity retaining wall is analyzed,the causes of cracks are summarized,and specific effective solutions are proposed.The results show that the method of unloading the retaining wall plus the anchor spray surface layer and steel pipe support can prevent the development of cracks.It can be seen that the reinforcement scheme of slope cutting,sloping,anchor shotcrete surface course and steel pipe support can ensure the safety of gravity retaining wall.
