Abstract

This paper combined the diseases such as slope instability occurring during the implementation of the complex joint project Shihui Interchange along the route from Shizhu, Chongqing to Qianjiang Expressway. Based on this, it explored the ideas and methods for selecting interchange schemes under mountain eolluvial deposits. The interchange's location has complex terrain and geological conditions, with many extreme weather events such as rainstorm. During studying the interchange schemes, the stability calculation should be carried out by fully combining the objective conditions and the cause of diseases. Additionally, the current terrain should be employed as more as possible to avoid protruding bad geological ranges, with the route to be flexibly extended. The interchange alignment indicators need to be controlled in combination with the actual conditions of bridges, subgrade protection and other projects. The indicators such as functionality, safety, economy, and applicability need to be considered to determine the final design scheme.
