山地项目中换填与桩基础的应用研究

Study on the Application of Project Replacement and Pile Foundation in Mountainous Projects

山地地区施工现场条件有限,为了保证工程项目基础部分的施工质量,提升桩基础的承载能力,论文以某实际山地项目为例,梳理了换填软土层施工的施工要点,从钢筋混凝土预制桩施工与切坡临边局部开挖桩基施工两个方面总结了桩基础的施工要点,为后续施工工序奠定基础。

The construction site conditions in mountainous areas are limited.In order to ensure the construction quality of the foundation part of the engineering project and improve the bearing capacity of pile foundation,this paper takes an actual mountain project as an example to sort out the key construction points of replacement construction of soft soil lager,summarizes the key points of pile foundation construction from two aspects of reinforced concrete precast pile construction and partial excavation of pile foundation near slope cutting,which lays a foundation for the subsequent construction process.
