１前言用动力试桩法检测桩身结构完整性、混凝土质量、并测定单桩承载力，是岩土工程技术人员多年来追求的目标。在工程界，低应变法动测单桩承载力的可靠性，被许多人怀疑；而高应变法动测单桩承载力则被看作是有希望部分代替静力试桩的方法，在国际上获得广泛的认可。高... 1 Preface It is the goal pursued by geotechnical engineers over the years to test the structural integrity of the pile body, the quality of concrete and the bearing capacity of single pile by dynamic test pile method. In engineering, the reliability of low-strain method to measure the bearing capacity of single pile is suspect by many people. However, the high-strain method to measure the bearing capacity of single pile is regarded as a promising method to replace static test. On the widely recognized. high...
