| 摘 要： | 先张法预应力钢筋混凝土预制管桩端板存在巨大市场，分析了管桩端板构件群边与法兰的生产工艺，指出法兰预制坯的生产方法决定端板的产品质量和生产成本。比较当前三种工艺生产法兰预制坯的质量和成本，揭示直接浇铸预制坯有切向残余拉应力的科学依据，为消除残余拉应力提出建议。

| Abstract: | In this paper proposing that pretensioning method prestressed reinforced concret precast pipe piling sheet has great market. Analysing the process of pipe piling sheet members periphery and flange. Pointing out processing method of flange precasted semifinished methods to defermine on sheet's guality and cost, comparing with quality and cost of the current three technology producting flange precast semifinished mentals, to reveal socience basis of direct casting precast semifinished mentals of trangential residual tensile stress. The proposals of estiminating residual tensile stress are put forward. |
