针对一般基坑，通常围护设计从节约成本的角度出发，采用φ609×16钢管斜抛支撑+施加预应力的方法，来有效控制基坑变形。本工程基坑东侧围护采用超长双拼φ609×16钢管斜抛支撑（最长为29.4 m）+局部单钢管支撑，并取得了较好的综合效益。
침대일반기갱，통상위호설계종절약성본적각도출발，채용φ609×16강관사포지탱+시가예응력적방법，래유효공제기갱변형。본공정기갱동측위호채용초장쌍병φ609×16강관사포지탱（최장위29.4 m）+국부단강관지탱，병취득료교호적종합효익。
To the general foundation pit, enclosure design us-ual y from the view of cost, using methods ofφ609 × 16 steel projectile support+prestressed, to effectively control the defo-rmation of foundation pit. The east of the engineering found-ation pit enclosure using long two-partφ 609 × 16 steel pipe left oblique support (up to 29.4 m)+partial single pipe support, and achieved good comprehensive benefits.
