摘　　要：SMW工法亦称新型水泥土搅拌桩墙,即在水泥土桩内插入H型钢等(多数为H型钢,亦有插入拉森式钢板桩、钢管等),将承受荷载与防渗挡水结合起来,使之成为同时具有受力与抗渗两种功能的围护墙。论文介绍了SMW工法替代传统钻孔灌注桩作为支护形式在杭州某项目基坑中的应用情况。阐述了SMW工法的施工原理和工艺,并结合工程实践,验证了SMW工法在深基坑工程应用上的实用性和可靠性。The SMW method,also known as a new type of cement-soil mixing pile wall,that is,the H-beam is inserted into the cement-soil pile(mostly the H-beam,sometimes Larsen steel sheet pile or steel pipe),which combined load bearing with the anti-seepage and water-blocking,making it a retaining wall with both supporting and impervious properties.This paper therefore,introduces the application of SMW construction method instead of the traditional bored pile as a supporting form in the foundation pit of a project in Hangzhou.The construction principle and technology of SMW construction method are described,and the practicality and reliability of SMW construction method in deep foundation pit engineering are verified by combining engineering practice.
