随着社会经济的不断发展,城市建设的进程不断加快,高层或超高层的建筑也越来越多。但由于城市空间和土地资源受限,这些高层或超高层的建筑在进行超深基坑开挖时很难进行放坡施工。因而,如何制定安全、有效的基坑支护结构体系是个重要课题。逆作法超深基坑支护结构体系作为一种城市施工当中的重要支护技术,在实际应用中发挥着良好的效果。本文以佛山国际商业中心二期工程为例,对逆作法超深基坑支护结构体系进行了有限元分析。
With the continuous development of society and economy, the process of urban construction is accelerating and more and more high-rise or super-tall buildings are being built. However, due to limited urban space and land resources, these high-rise or super-tall buildings are very difficult to carry out slope excavation during excavation of ultra deep foundation pit. Therefore, how to formulate a safe and effective foundation pit supporting structure system is an important issue. As a kind of important supporting technology in urban construction, the super-deep foundation pit supporting structure system with reverse working method plays a good effect in practical application. Taking Foshan International Business Center Phase II project as an example, finite element analysis is conducted on the underbracing ultra deep foundation pit supporting structure system.
