PHC管桩桩身质量检测中多种方法的综合应用
PHC管桩桩身质量检测中多种方法的综合应用
摘要:简要介绍了低应变动测法、静载试验、孔内摄像方法的原理及其优缺点。当多节PHC管桩静载承载力结果与勘察参数预估结果差别较大时,对管桩桩身较深缺陷产生怀疑时,低应变方法无法明确,可以采用孔内摄像方法,较为直观地了解缺陷的深度和程度,从而提高检测结果的可靠性,并通过工程实例进行说明。望能为类似工程的设计和缺陷处理提供借鉴。
Abstract:low strain measurement method,static load test and intra-hole imaging method are briefly introduced about The principle、advantages and disadvantages.When the static load bearing capacity of multi-section PHC pipe piles differs greatly from the prediction results of survey parameters and there are doubts about the deep defects of the pipe pile,the lowstrain method cannot be clarified,and the intra-hole imaging method can be used to understand the depth and extent of defects to improve the reliability of the test results and explained them through engineering examples.Hope to provide reference for the design and defect processing of similar projects.
