深基坑支护设计及施工

Design and construction of supporting of deep foundation pit

通过石家庄“长安广场”工程实例，阐述利用干作业成孔钢筋混凝土灌注护坡桩、预应力混凝土锚杆、非预应力混凝土锚杆、插筋补强、挡土墙、构造柱等技术进行深基坑支护．

By actual engineering example,the paper discusses the technology of concreted steel revetment pile under dry construction,prestressed concrete anchorage pole,concrete anchorage pole,reinforcing bar for strength,retaining wall,structural column for supporting of deep foundation pit.
