摘要
刚性桩复合地基在一些地区已开始在高层建筑中应用,为了了解带褥垫层复合地基在水平荷载与竖直荷载共同作用下的工作性状,进行了一系列模型试验,并在试验的基础上分析了不同垂直荷载、不同褥垫层厚度对水平荷载作用下的桩顶、桩身及褥垫层顶部水平位移的影响,揭示了基础—褥垫层—桩在水平荷载作用下的相互作用机理。
The composite foundation with rigid pile has been used under tall buildings in some areas. In order to understand the behavior of composite foundation under horizontal load, a series of model tests were performed to investigate the effects of different vertical load and thickness of cushion on horizontal displacements of pile head, pile body and the top of cushion under horizontal load, and to reveal the mechanism of interaction of foundation-cushion-pile under the horizontal load.
