摘要:
针对湛江钢铁焦炉项目打入PHC桩施工中出现的桩基上浮问题，在采用常规的竖向静荷载试验发现承载力不足之后，再采取土体破坏后继续加载试验、独桩静荷载试验和复压后静荷载试验等方法，研究软土地基桩基上浮现象、原因和处理措施。
Aimed at the pile up-floating problem of the driven PHC piles of the Zhanjiang Steel coke oven project, a conventional vertical static load test indicates that the load capacity is insufficient. Then further test methods, such as post soil failure successive load tests, single pile static load tests, post re-driving static load tests, are taken, and the pile up-floating phenomena, reason and treatment measures are studied.
