Can Static Load Test Reflect True Conditions of Composite Foundation?

摘要: 探讨了静载试验用于复合地基承载力确定时的可靠性。认为单桩试验与真实情况下的复合地基的工作性状有很大的差别,而载荷板试验又存在不利的尺寸效应,因此复合地基上的静载试验能否反映真实情况值得研究。在对静载试验的不利因素分析的基础上,提出了有关的设计建议。Abstract: The reliability of the test for composite foundations deserves solid consideration,because the condition of single pile load test is far from that of the composite foundations,and the load board test of composite foundation has obvious size effect compared with buildings in true conditions.Based on the analysis of the affecting factors,put forward some useful opinion for design purposes.
