随着我国经济的高速发展,建设项目规模的越来越加大,深基础施工技术及深基坑支护技术也得到了广泛应用,但深基坑工程施工安全性较大,风险性较高,基坑失效、失稳的安全质量事故时有发生,究其原因除设计不够完善外,主要是基坑支护结构施工质量达不到设计要求、土方开挖不合理以及降排水处理不当等造成的。
With the rapid economic development in our country, the scale of construction projects is getting larger and larger. Deep foundation construction technology and deep foundation pit supporting technology have also been widely used, but the construction of deep foundation pit construction is more secure and has a higher risk , Pit failure, instability, safety and quality accidents have occurred, the reasons for the design is not perfect, the main pit supporting structure construction quality not meet the design requirements, excavation unreasonable and improper drainage and drainage treatment Caused.
