单桩竖向承载力静载荷试验和高应变动力检测对比试验研究

he Comparative Test Research of Single Pile’s Capacity of Enduring Compressive through Static Load Test and Dynamic Test Method

中文摘要英文摘要

单桩竖向承载力静载荷试验过程与桩在工作状态下的受力过程基本一致,是传统而可靠的承载力检测方法该方法,是确定工程桩承载力最直观、最准确可靠的方法,缺点是费时费钱,抽检率不高;高应变动力检测是建立在一维波动理论基础上的承载力检测新方法,其特点是费用低、快速、轻便,但技术难度较大且存在多解性。目前的桩基检测通常采用静荷载试验法和高应变动测试验法对单桩竖向抗压承载力进行检验,并以前者作为后者试验结果的对比标准,文中通过对摩擦桩动静检测数据进行对比分析,以检验动测法承载力的精度,并讨论导致两者差异的因素。

he process of the single pile’s capacity static load test is generally consistent with the process of the working pile. It’s the traditional and reliable method to test the pile’s capacity, and it’s the most intuitive and reliable method. But the method need plenty of time and money, and the sampling rate is low. The dynamic test is the new method to test the capacity which established in the one-dimensional wave motion theory. The method is economical fast and facile, but it’s difficult in technology and muti-solutional.At present, we usually chose static load test and dynamic test method to test the single pile\
