摘要:
整体强制反应位移法采用土-结构相互作用模型,将地震作用下的土层位移以强制位移的方式施加到整个土层上,从而计算结构在地震作用下的响应。本文以天津某地铁盾构隧道为例,采用整体强制反应位移法进行地铁盾构隧道结构的抗震分析计算。为了验证该方法在复杂软土场地下盾构隧道结构抗震分析中的适用性,以时程分析法为基准,对比分析整体强制反应位移法、反应位移法和时程分析法3种方法计算出的盾构隧道结构内力图和内力峰值。研究表明,整体强制反应位移法具有较好的适用性及易操作性,具有较高的计算精度,是一种方便有效的抗震设计拟静力方法。
Abstract:
The integral forced response displacement method, which adopts soil-structure interaction model, applies the displacement of the soil layer under earthquake to the whole soil layer in the form of forced displacement, and calculates the response of the structure under earthquake. Taking an underground shield tunnel in Tianjin as an example, this paper adopts the integral forced response displacement method to analyze and calculate the seismic analysis of subway shield tunnel structure. In order to verify the applicability of this method in seismic analysis of shield tunnel structures under the complex soft soil field, the internal force diagram and internal force peaks of the shield tunnel are calculated by three methods including the integral forced response displacement method, the response displacement method and the time-history analysis method, and the results are compared and analyzed on the basis of the results of the time-history analysis method. The results show that the integral forced response displacement method has good applicability, simple operability and high accuracy, and is a convenient and effective quasi-static method for seismic design.
