摘要
依据现行设计规范,论述正常使用极限状态下和承载能力极限状态下桩身承受轴心拉力时配筋设计和裂缝控制。并结合工程实例,讨论抗拔桩设计的计算方法,从而为抗拔桩的设计与计算的安全准确提供依据。
Based on the code for seismic design and pile foundations of building,the key points of pile designing and crack controlling under the serviceability limit states and ultimate limit states are explained apparently.Methods of calculating have been summarized and the results can be used as reference to the course of design,according to the real example.
