摘要
结合境外某跨海大桥的钻孔灌注桩试桩的静载试验成果,分析可能造成试桩竖向承载力不满足要求的影响因素。分析结果表明:土的应力释放、桩侧光滑度(尤其是桩侧泥皮)和桩端页岩强风化层饱水软化等因素是造成试桩承载力不足的主要原因。
Analyzing the factors affecting bearing capacity of vertical bored piled by comparing overseas bored pile static load test results. The results show that the stress release of soil, pile smoothness （especially the pile shaft skin surface） and soft- ening of highly weathered saturated SHALE layer are the main factors for affecting the bearing capacity of the pile.
