礫卵石層中運用大壩帷幕灌漿技術進行基
坑止水和支護的可行性和經濟性。
Abstract : the traditional method of anchor pile on the deep foundation pit bracing in the gravel stratum with high hardness, poor drilling and easy slump is complicated owing to difficult construction, low efficiency and high cost
文摘:卵礫石地層硬度大,可鉆性差,易坍塌,這種地層的深基坑支護若採用傳統的錨桿樁,施工難度大,工效低,工程造價高。
