Abstract
Pile foundation bearing-retaining wall combination structure is a new type of support structure developed in recent years. This article focuses on the characteristics, advantages, and application scope of the support structure, while combining a variety of algorithms, according to different geological conditions and slope stability, as well as summarizes the pile foundation bearing-retaining wall combination structure force analysis and design methods, taking a high-fill road project in Chongqing as an example. The application of this support structure under special conditions, such as thicker soil layer, steeper sliding surface, weak foundation, and limited slope release conditions, is presented, which illustrates the technical advantages of this support structure and proving that it has several other advantages, including clear force mechanism as well as economic and reasonable structure, thus providing reference for similar projects.
