| 摘 要： | 根据传递法思想，利用矮桥墩以剪切变形为主的特点，结合桩一土作用等效原理，推导了层状场地及矮桥墩结构的传递计算公式，给出了在层状场地中基岩输入谐振波情况下矮桥墩的动力响应分析计算过程，解决了层状场地中矮桥墩动力响应的分析计算问题。由于地震波可以用谐振波的组合进行解析，因而为解决层状场地中矮桥墩的抗震分析及计算提供了一种新方法。 |

| Abstract: | According to transfer ideas, using the characteristics of dwarf pier＇s shear deformation primarily, combined with the pile-soil interaction equivalence principle, derived the transfer calculation formula of the layered site and the dwarf pier structure, gives the dwarf pier dynamic response analysis and the calculation process when input harmonic wave in layered bedrock, solved the analysis and calculation＇s the problem in layered dwarf piers of dynamic response. Due to the seismic wave can be parsed by combination the harmonic wave, this paper is to solve the problem of layered dwarf pier＇s anti-seismic analysis and calculation provides a new method. |
| Keywords: | structural calculations layered site dwarf pier pile-soil interaction shear harmonic wave transfer matrix |
