复杂地质条件下密集桩群中塔式起重机基础施工研究探讨

DISCUSSION ON FOUNDATION CONSTRUCTION OF TOWER CRANE IN DENSE PILE GROUP UNDER COMPLEX GEOLOGICAL CONDITIONS

针对基坑中出现的塔式起重机桩基础形式,并结合施工现场实例,阐述了于现场复杂地质条件下密集桩群中塔式起重机基础施工的设计内容与施工流程。对塔式起重机基础定位布置相关考虑因素进行举例说明,并通过设计验算解释桩基施工与塔式起重机承台设计的相关设计思路与要点,在此基础上指出对应环境条件下塔式起重机基础施工中应注意的问题事项。

In view of the tower crane pile foundation form appearing in the foundation pit, and combined with the construction site example, the design content and construction process of the tower crane foundation construction in the dense pile group under the complex geological conditions of the site are expounded. The relevant considerations for the positioning and layout of the tower crane foundation are illustrated with examples, and the relevant design ideas and key points of the pile foundation construction and the tower crane cap design are explained through the design check calculation. On this basis, the problems that should be paid attention to in the tower crane foundation construction under the corresponding environmental conditions.
