【摘要】：针对大吨位灌注桩开展动静对比研究,指出高应变法在大吨位灌注桩领域应用较少原因,结合实际工程进行动静对比,结果显示检测桩高应变拟合分析和静载检测结果吻合性较好,证明拟合分析采用的桩土模型、参数是合理的。针对有些地方动静对比的误区,指出无须刻意追求检测值的差异,只要选用的桩土模型、参数合理,二者差值不大即可。对于高应变检测中存在疑问的桩应采取其它方法进行验证,各种基桩检测方法取长补短,共同发展。
[Abstract]:According to the comparative study of static and dynamic development of large tonnage pile, it is pointed out that the high strain in large tonnage pile seldom used, combined with practical engineering, static comparison, results show that the detection analysis of high strain pile static load test and the fitting results are in good agreement with that of pile-soil model fitting analysis, the parameters are reasonable. Aiming at the misunderstanding in some places, dynamic and static comparison, points out that no difference the deliberate pursuit of detection value, as long as the pile-soil model, selecting reasonable parameters, the difference between the two is not in doubt. For high strain test pile should take it to verify the method of various pile testing methods, common development.

【正文快照】： 0引言静载荷试验法和高应变法是目前基桩承载力检测最常用的方法。静载荷试验法是在当今技术水平下基桩竖向抗压承载力最准确的方法,但由于其成本高、检测周期长、对场地要求高,使其在某些领域、某些工程上的使用受到一定限制。高应变法具有检测周期快、成本小的特点,但受场地
