SMW工法在地铁静安寺站5号出入口下沉式广场基坑围护工程中的应用

The Application of the SMW Method in the Supporting Wall Engineering of the Sinking Square Connecting No. 5 Gangway of JingAnSi Metro Station

在地铁静安寺站5号出入口下沉式广场(以下简称下沉式广场)基坑围护工程中,采用了SMW工法。基坑开挖过程中严格遵循时空效应原则,做到分段、分层对称开挖,随挖随撑,使该种工法经受了盆式开挖施工方法的考验,围护效果良好。新颖的SMW工法,正以其优越的社会、经济效益而逐渐走向大型的深基坑工程施工领域。

The SMW method was selected in the supporting wall engineering of the sinking square connecting No. 5 gangway of JingAnSi metro station. The rule of Time-Space Effect was ex-ecuted strictly in the excavation procedure, in which the excavation was carried out in straticfication and segmentation and strutted closely following the excavation in order to guarantee the equilibrium of excavation. With this excavation method, the supporting wall constructed by SMW method showed a good effect. The new SMW method is more and more applied in the construction field of large excavation engineering due to the superior social benefit and economic benefit.
