徐州地区预应力方桩应用分析

Analysis on The Application of Prestressed Spun Concrete Square Pile Techniques in Xuzhou

预应力混凝土空心方桩作为一种新型的预应力混凝土桩结合了预应力混凝土空心管桩和混凝土预制方桩的优点。受上海倒楼事件和类似管桩质量事故的影响,目前江苏省徐州市对管桩的使用作出了部分限制。预应力方桩在徐州地区正处在大力推广阶段,但由于徐州地区地质情况复杂,不易直接套用其他地区的设计经验参数。本文结合工程实例对该技术在徐州地区的使用情况进行了检测并对结果进行了分析。得出了一些有益的经验参数。

The technique of prestressed spun concrete square pile is a new type of piles developed from prestressed pipe pile and prestressed square pile. For the influence of Shanghai pipe pile quality accident, Jiangsu province and Xuzhou city restrict with the application of pipe pile. So prestressed spun concrete square pile be extended to Xuzhou area. But Xuzhou has distinctive geology, it can not put other area design parameter to use in Xuzhou. This paper analyse prestressed spun concrete square pile monitor datas from civil engineering in Xuzhou. Which obtain some useful design parameters for analogous engineering in Xuzhou area.
