摘要
结合河北省故城县某风电场工程基坑周边场地环境(含交通道路等)、基坑开挖深度及地勘等资料,考虑安全性、可行性、经济性等因素,本项目基坑采用桩锚和土钉墙联合支护方案,同时在基坑桩间布置1排高压旋喷桩作止水帷幕,在基坑开挖过程中进行信息化施工,确保围护结构及周围环境安全与稳定。该基坑支护方案安全合理、施工可行、技术经济效益显著,为故城县地区风电场工程基坑支护提供了一定的实例经验。
Based on the site environment(including traffic road),excavation depth and geological survey data of a wind power project in Gucheng County,Hebei Province,the factors of safety,feasibility and economy are considered. The foundation pit of this project adopts the combined support scheme of pile anchor and soil nailing wall,and a row of high-pressure rotary jet grouting piles is arranged among the piles of the foundation pit to be used as water-stopping curtain,and the informatization construction is carried out during excavation of the foundation pit,to ensure safety and stability of the enclosure structure and surrounding environment. The scheme is safe and reasonable,feasible in construction and has remarkable technical and economic benefits. It provides some practical experience for foundation pit support of wind power project in Gucheng county area.
