摘　　要：基于某建筑项目的塔式起重机基础设计,采用桩顶水平位移与转角控制的计算方法,对单桩和多桩承台式塔机深基础的设计进行了对比分析。得出在满足塔基抗倾覆稳定性的条件下,与采用多桩承台式深基础相比,单桩承台式深基础能减小施工上的复杂性,减少材料用量,较大地降低工程造价。研究成果可为类似工程的塔基设计提供参考依据。Based on the tower crane foundation design of a construction project,the calculation methods of horizontal displacement and corner control of pile top were used.Foundation designs of single and multiple pile-supported tower crane were analysed respeptively.Comparing with using multiple pile-supported foundation,single pile-supported foundation can reduce the complexity of construction,the amount of material and the project cost greatly under the condition of meeting the anti-overturning stability of the tower crane.The results presented in this thesis are expected to provide valuable information for the tower crane foundation design in the future.
