这些年来,当城市建设飞快的发展,高层建筑飞速增多,基坑也相应变大。前些年,很多地方都使用的重力式支护结构对当前的工程已经无法满足,然而桩锚支护结构有着适应性强的特点,所以在深基坑支护工作里得到了很好的应用。当前,深基坑工程耗费的资金非常多,其中造价跟上部结构工程的造价不相上下。深基坑工程无论是在设计,施工还是监测方面都引发了非常广泛的重视。如何根据每一个基坑的实际状况,选择适当的支护方案,以及合理的支护体系设计方法,对于工程的安全来说是非常重要的。对现场的监测资料进行观察,将基坑的状况以及发展趋势进行判断,这也是深基坑支护的重要课题。
In recent years, with the rapid development of urban construction and the rapid increase of high-rise buildings, the foundation pit has also been correspondingly enlarged. In recent years, the gravity retaining structure used in many places has been unable to meet the current project. However, the pile-anchor supporting structure has the characteristics of adaptability and is therefore well applied in the deep foundation pit support work . At present, the funds spent on deep foundation pit projects are very large, of which the cost is comparable with that of superstructure projects. Deep foundation pit engineering has aroused a great deal of attention in terms of design, construction and monitoring. How to choose the proper supporting plan and how to design a proper support system is very important for the safety of the project according to the actual condition of each pit. Observation of the site monitoring data, the status of the pit and the development trend to judge, which is an important issue supporting deep foundation pit.
