摘要

建立了3种基础-土相互作用模拟方式,分别为考虑一定桩身柔性的固结独塔模型,基于"m"法的线性独塔模型,以及采用"p-y"曲线法的非线性独塔模型。采用El-Centro和Kobe两种地震波分别对3个模型进行计算分析,结果发现,基于"m"法的线性独塔沉井模型与"p-y"曲线法的非线性独塔沉井模型相比响应偏大,而基于"m"法的线性独塔群桩基础模型则与"p-y"曲线法的非线性独塔群桩基础模型有较好的吻合。
Three different models are discussed in this paper,which are consolidation single tower model with body flexibility considered,linear single tower model based on m analysis method and nonlinear single tower model based on p-y curve analysis method,respectively.Seismic responses of these models are analyzed under ground motion inputs of El-Centro Earthquake and Kobe Earthquake and the calculation results are compared in this paper.The result turns out that the simulation method of linear single tower model of open caisson based on m analysis method produces larger structual response than that of the nonlinear single tower model based on p-y curve analysis method.While the simulation method of linear single tower model of pile group foundation based on m analysis method matches very well with that of nonlinear single tower method based on p-y curve analysis method.
