摘要
在地质较为软弱的区域进行构筑物施工和基坑开挖易造成周边支护变形,从而引起基坑周边地表沉降,影响工程的质量和进度。为此,文章分析影响地表沉降的诸多因素,针对一些基坑开挖沉降控制的难点工程,介绍几种优良的基坑支护和沉降控制方法,并对各种控制方法的施工要点和优势进行阐述,以期能够提高类似工程的施工效率及安全性。
In the area of weak geology,the construction of structures and excavation of foundation pit are easy to cause deformation of surrounding support,thus causing ground settlement around the foundation pit,affecting the quality and progress of the project.Therefore,this paper analyzes many factors that affect the surface settlement,introduces several excellent foundation pit support and settlement control methods for some difficult projects of foundation pit excavation settlement control,and expounds the construction key points and advantages of various control methods,in order to improve the construction efficiency and safety of similar projects.
