Study on the Composite Foundation with Cement-Flyash-Gravel Pile
-
摘要: 本文根据室内模型及现场原位试验，对水泥粉煤灰（ＣＦＧ）桩复合地基褥垫层的作用，垂直荷载作用下桩、土荷载的分担，复合地基变形性状进行了探讨。阐述了ＣＦＧ桩复合地基设计思想，并给出了相应的设计计算方法。Abstract: According to the laboratory and in situ tests, this paper discusses into the roles Of the mattress of compositefoundtion with cement, fly-ask, gravel pile （CFGP）, the bearing ratio of CFGP to soil under the vertical loads, and thedeformation behaviour of the compsite foundation. The Paper also sets forth the design ideas of CFGP composite foundationand the rdevant maculating method.
