摘要
根据太原武宿国际机场三期改扩建工程项目设备共同沟区域深基坑施工需求及复杂地质环境条件,在小锁口拉森钢板桩应用的基础上,从液化深基坑支护体系的总体部署、设计参数及施工要点的角度系统总结了以拉森钢板桩为主,高压旋喷桩、卸土放坡为辅的创新支护体系的应用经验,在项目上取得了很好的效果,节省了材料和工期,有利于推进绿色施工,形成了良好的示范作用。
According to the construction requirements and complex geological environment conditions of deep foundation pit in common ditch area of equipment of Taiyuan Wusu International Airport Phase III renovation and expansion project,based on the application of small suokou Larsen steel sheet pile,this paper systematically summarizes the overall deployment,design parameters and construction points of liquefaction deep foundation pit supporting system with Larsen steel sheet pile as the main part.The application experience of the innovative support system supplemented by high-pressure rotary jet pile and soil discharge has achieved good results in the project,saving materials and construction period,which is conducive to promoting green construction and forming a good demonstration role.
