【摘要】：如今我国的城市建设在高速发展中,城市可用的建设用地越来越少,高层建筑和超高层建筑工程如雨后春笋的涌现,地下结构工程的埋深也越来越大,基坑工程的设计要求也越来越高，同时对应施工难度也越来越大，而国家相关行政主管部门对于基坑的安全性要求也越来越重视，制定了多项政策来加强对基坑施工的监督管理，，确保基坑的安全。深基坑支护工程虽然大部分都属临时性工程,但因其对外界环境变化较敏感，受不确定性因素影响太多，而且施工技术复杂,其施工难度有的却远远超过永久性的基础结构，同时它也是一个非常系统工程,潜在危险性大、是确保后续永久性结构施工的前提,所以它的重要性不言而喻，是土建工程管理中的一个重要环节。本文阐述在不同的环境条件下如何选择合支护方式，以及如何明确基坑支护施工管理中的难点及重点，如何通过相应的管理及技适的基坑术措施来确保基坑的安全。本文结合中惠璧珑湾项目实际的工程案例,就深基坑支护施工管理重点及方法等进行分析探讨。
[Abstract]:Nowadays, with the rapid development of urban construction in our country, there are less and less land available for urban construction. The emergence of high-rise buildings and super-high-rise building projects and the underground structure projects are also becoming more and more deep. The design requirements of foundation pit engineering are more and more high, and the corresponding construction is becoming more and more difficult, and the relevant administrative departments of the state also pay more and more attention to the security requirements of foundation pit. A number of policies have been formulated to strengthen the supervision and management of foundation pit construction to ensure the safety of foundation pit. Although most of the deep foundation pit support works are temporary projects they are more sensitive to the changes of external environment. Too many uncertain factors, and complex construction technology, some of its construction difficulties are far more than permanent infrastructure, at the same time, it is also a very systematic engineering, potentially dangerous. It is the premise to ensure the subsequent construction of permanent structure, so its importance is self-evident, is an important link in the management of civil engineering. And how to clarify the difficulties and key points in foundation pit supporting construction management, and how to ensure the safety of foundation pit through the corresponding management and technical measures. This paper combined with the actual project case of HuiBilong Bay Project. The key points and methods of deep foundation pit supporting construction management are analyzed and discussed.
