护壁桩作为塔吊基础的理论设计及应用

Theoretical Design of Retaining Pile as Tower Crane Foundation and the Successful Application

摘要:

通过鞍山第一高楼----鞍山国际明珠大厦深基坑护壁桩作为塔吊基础的理论设计及成功应用的工程实例，详细介绍了深基坑支护中护壁桩在作为基坑支护的主要结构的同时，又可以通过理论与实际的相互转化，从而又能承担塔吊基础载体的这一大胆设计，成功解决了许多狭小地带修建高层时塔吊安置的难题。以此理论计算为依据，可以举一反三，解决集中荷载在基坑设计中如何取值并且转化成模型，为今后类似工程提供经验。

Abstract:

By the engineering case of the theoretical design of retaining pile as tower crane foundation for the first-high building in Anshan-Anshan International Pearl Building, the paper introduced that the retaining pile was constructed not only as the main structure of foundation pit support but also as the carrier of the tower crane. This bold design successfully resolved the difficulty of tower crane installation in many narrow sites. Based on this theoretical calculation, the concentrated loading valuetaking in the foundation pit design would be solved and be transformed into the model to provide reference for similar engineering in future.
