摘要
分析预应力大管桩接缝位置的受力特性,对接缝处产生的局部压力作用位置、作用面积和作用强度对桩身内部应力的影响因素进行系统的研究,为深入分析大管桩制桩过程中桩身应力变化和改进措施提供可靠的理论依据。
The influence of the acting position, acting area and strength of load factors on the internal stress of pile at the joint is studied systematically. It provides a reliable theoretical basis for in-depth analysis of pile＇s stress variation and improvement measures during making of large-diameter pipe pile.
