摘要
CFG桩复合地基目前广泛应用于土木工程各个领域,对其桩-土共同作用机制的研究具有重要意义。通过对CFG桩复合地基在安徽蚌埠某高层建筑中现场测试项目的资料分析,得出了CFG桩的桩-土应力分担的变化规律。测试结果显示,随着外加荷载的增加,桩-土应力比比例增加。当施工荷载为250 kPa时,桩-土应力比为26并趋于稳定。
The CFG pile-composite foundation is widely applied in civil engineering fields, of the pile-soil interaction is of great significance. By actual testing data of a high-rise bulding the study in Anhui Bengbu, the stress characteristic of CFG piles and the variety law of soil stress between piles are ob- tained. According to these ements, pile-soil stress ratio increases with the increase of the imposed is 250 kPa, the vertical stress of the CFG pile is about 26 times bigger load. When the construction load than the earth stress between pile.
