摘要
由于地质条件的不确定性及复杂性,造成了深基坑工程的高风险性和高难度性。本文在综合分析广元银河金岸深基坑已有地质资料及场地周边环境的基础上,确定对研究区深基坑降水采用管井法,基坑支护则根据周边环境差异,分两段分别采用排桩+锚索和放坡+土钉墙两种方案进行支护设计,并对排桩+锚索、土钉墙和降水井施工要点进行了分析与探讨。
Deep foundation project is with high-risk and huge difficulty becaused byof the uncertaintynondeterminacy and complicacy of geological condition. Based on the geological data and surrounding environment situation of Yinhejinan deep foundation in Guangyuan, tube well method iwas chosen to descend the hypsogramhydrometeor. Four methods such as piling with anchor wire, and slope with soil nailing wall awere used in this engineering depended on the diversity of surrounding environment. Furthermore, construction technologies of piling, anchor wire, soil nailing wall and hydrometeor well awere analyzed and investigated in this paper.
