Abstract
The G664 reconstruction project of the Shangri-la-Geka(Sichuan-Yunnan boundary)section in Daocheng County is a major highway project located in the alpine plateau area of western Sichuan which spans a total length of 57.311 kilometers and includes various engineering contents such as tunnels,bridges,and culverts.This paper mainly introduces the anti-slide pile construction technology in this project,focusing on analyzing the hole forming method of pile foundation joist,pile foundation design and construction methods,and safety measures taken during the construction process.The project adopts the bored cast-in-place pile construction technique,which successfully overcomes the technical challenges of pile foundation construction under complex geological conditions.Through strict control of pile foundation construction quality and implementation of safety technical measures,the project effectively ensured the stability and safety of the structure.At the same time,this paper also discusses environmental protection measures taken during the construction process and flexible response strategies to deal with complex geological changes.This research provides strong technical support and valuable experience for similar projects,and has important reference value.关键词
