地下道路结构中反应位移法计算参数影响分析

Analysis on Influence of Calculating Parameters of Response Displacement Method in Underground Road Structure

摘要:

在已有研究的基础上，针对地下道路结构中反应位移法各计算参数对计算结果的影响进行相关探讨，建立多个模型对比分析。结果表明，对于某一特定地区的单层地下道路结构而言，地震作用下结构最不利位置处于结构覆土厚度最大、基准面深度最小、土体剪切波速最大处。结构横断面宽度对结构各内力的影响不尽相同，需具体分析。

Abstract:

On the basis of the existing research, the influence of the calculating parameters of the response displacement method in the underground road structure on the calculation results is discussed. The multiple models are established for comparative analysis. The results show that for a single-layer underground road structure in a particular area, the most unfavorable position of the structure under the action of an earthquake is located at the most thickness of the soil covering, the smallest depth of base level and the maximum velocity of soil shear wave. The influence of the cross section width of the structure on each internal force of the structure is not the same, which requires specific analysis.
