摘要
通过对王曲、蒲城两个大型浸水试桩工程实例的地质条件、试验方案和试验结果的阐述和对比 ,分析了其静载荷作用下Q S曲线及桩身内力的异同点 ,指出了湿陷性黄土地基现场浸水试验的必要性以及目前存在的问题 ,提出了浸水状态下 ,加荷过程不同 ,对单桩最终沉降量影响较大 ,而对单桩极限承载力值影响甚小的结论。
Identities and differences of Q\|S curves and inner force of pile shaft under static load are analyzed herein through the statements and tests carried in two projects of large scale.The necessity of field immersion tests for collapsible loess ground and problems existing at present are pointed out.A conclusion that under condition of water immersion with different procedures of loading the impact on final settlement of single pile is big but the impact on ultimate carrying capacity of single pile is small is proposed.
