| 摘 要： | 本文通过对分层弹性地基中单桩基础按Ｗｉｎｋｌｅｒ（温克尔）地基土模型特性分析，建立了合理的力学模型。通过动力分析，给出了桩基础横向自振特性及在横向动力与地震载荷作用下强迫反应的解析解。文中的解析公式为分层弹性地基中单桩基础在横向动力与地震载荷作用下的动力反应分析提供了一种新的解析方法。

| Abstract: | In this paper,a reasonable mechanics model is established to the single pile foundation inelasto stratum according to the characteristic analysis of the Winkler model of elato stratumsoil. We gave the features of the lateral free vibration of pile foundation and the analytical solutionof coercion response under the action of lateral impetuses and lateral seismic loads.We provided anew analytical method for the impetus response analysis of the single pile foundation in elasto stratum underthe action of lateral impetuses and lateral selsmic loads using the analytical formulaein this paper. |
