摘要
利用双排钢筋混凝土钻孔灌注桩+锁口梁+矩联扩大头锚杆的综合支护技术,在大面积(近5万m2)超深(15.86 m)基坑支护工程中得到了成功应用,取得了超深基坑支护工程施工的新经验。
Combination of technology including duplex reinforced concrete boring cast-inplace pile,concrete locking beam,and bit expanded anchor rod is employed for large-scale(50 000 m^3) deep(15.86 m) excavation support,and new experience in construction of extra-deep excavation support is gained.
