地震作用下支挡结构的设计式研究

在地震作用下如何选取路基支挡结构构件的设计式，是规范编制所急需解决的问题。针对该问题，首先，在系统地梳理了国内第一，二，三层次可靠度设计标准的基础上，提出3种地震组合设计式；其次，运用所编写的路基支挡结构设计软件，进行极限状态设计及可靠性分析对比验证，最终提出地震作用下路基支挡结构构件的设计式。该设计式可对路基支挡结构设计规范的编制提供更为准确的依据。

Study on the Design Form of Retaining Structure under Earthquake Design Situation

To obtain the design form of retaining structure of subgrade under earthquake design situation is an urgent problem to be solved for code compilation. According to this problem, firstly, On the basis of systematic analysis of a series of reliability design standards of China, three kinds of design forms of retaining structure of subgrade under earthquake design situation are proposed. Secondly, using the software of retaining structure of subgrade to compare and verify the result of limit state design and reliability index. Finally, the design form under earthquake design situation is obtained. This result can provide a more accurate basis for the compilation of the code for design on retaining structure.
