以石灰岩为持力层的CFG桩复合地基应用研究

The application study of limestone used as bearing course of the CFG pile composite foundation

本文通过实例说明了CFG桩复合地基在石灰岩地区的适用性和优越性。并采用ANSYS有限元软件对单桩复合地基进行数值模拟,模拟值与理论值比较,更接近实测值,说明了数值模拟有相当的可靠度,为研究以石灰岩为持力层CFG桩复合地基提供了新方法。

Through example, the paper fully demonstrates adaptability and advantage of the CFG pile composite foundation in the limestone area. And it simulate the pile composite foundation using ANSYS finite element software.sinmlation compared with the theoretical value is closer to the measured values.This result indieates simulation is eonsiderable reliable and provides new means to study the CFG pile eomposite foundation using limestone as bearing eourse.
