Method for detecting and evaluating bearing capacity of prefabricated pipe pile
The embodiment of the invention provides a prefabricated pipe pile bearing capacity detection and evaluation method, and relates to the technical field of civil engineering and traffic engineering. The method comprises the steps that preset pile side friction resistance data and preset compression bearing capacity data of the prefabricated pipe pile are obtained; theoretical pile end resistance data are obtained according to the preset pile side friction resistance data and the preset compression bearing capacity data; total load data and actually-measured pile end resistance data of the prefabricated pipe pile in the pile sinking construction process are obtained, wherein the actually-measured pile end resistance data are collected through a gasket sensor; if the total load data is greater than or equal to the preset compressive bearing capacity data and the actually measured pile end resistance data is greater than or equal to the theoretical pile end resistance data, the sinking construction of the prefabricated pipe pile is stopped; and according to the total load data and the actually-measured pile end resistance data, the vertical compression bearing capacity of the pipe pile in the long-term use stage after pile sinking is obtained. The method can replace a pile foundation compression resistance static load test to obtain the vertical ultimate bearing capacity of the tubular pile, the pile foundation bearing capacity detection cost is reduced, and the pile foundation construction period is shortened.
本申请实施例提供一种预制管桩承载力检测与评估方法，涉及土建与交通工程技术领域。该方法包括：获取预制管桩的预设桩侧摩阻力数据和预设抗压承载力数据；根据预设桩侧摩阻力数据和预设抗压承载力数据获得理论桩端阻力数据；获取预制管桩的沉桩施工过程总荷载数据和实测桩端阻力数据，其中实测桩端阻力数据通过垫片传感器进行采集；若总荷载数据大于等于预设抗压承载力数据、且实测桩端阻力数据大于等于理论桩端阻力数据，预制管桩停止下沉施工；根据总荷载数据和实测桩端阻力数据，获得管桩沉桩后长期使用阶段的竖向抗压承载力。该方法可代替桩基抗压静载试验获得管桩竖向极限承载力、减少桩基承载力检测费用、缩短桩基施工工期的技术效果。
