摘要：

通过从几个角度比较试验区灌注桩的静载试验结果,分析了灌注桩经后压浆处理承载力提高的幅度以及影响承载力的因素。分析了后压浆处理灌注桩承载机理。对试验桩的测试龄期及荷载分级提出了建议。为工程设计提供准确数据。

The amplitude of improvement of the bearing capacity of bored cast-in-situ concrete piles after being treated with post pressure grouting and the factors affecting the bearing capacity were analyzed on the basis of the comparisons of the results of static load testing of bored cast-in-situ concrete piles in a pilot area in Tianjin Port from different angles.The mechanism of improvement of the bearing capacity of the bored cast-in-situ concrete piles after being treated with post pressure grouting was also analyzed and recommendations were also proposed for the determination of the time to carry out the tests of the piles and the division of stages of the loads to be imposed on the piles in order to provide accurate data for engineering designs.
