摘要
本文分析了灌注桩高应变检测中存在的各种问题,指出可能影响拟合分析结果精度的主要因素,并通过某检测实例的动静对比分析,证明高应变法应用于桩身完整性和单桩极限承载力推定是可行的,可作为大直径灌注桩静载试验的有效补充。
This paper analyzes the various problems in the high strain dynamic testing of cast-in-place piles,and points out the main factors that probably influence the curve match accuracy.According to the dynamic statistic ratio of the testing case,it is proved that the high strain dynamic testing is feasible to test the pile integrity and the ultimate bearing capacity of single pile,therefore,it can be used as an effective supplement of the static load test of the large diameter piles.
