摘　　要：依据现场试验资料,对比研究采用不同水灰比、下钻速度下的SMW工法桩对深层土体位移的影响,结果表明水灰比1.2、下钻速度50mm/min比较适用,可为邻近运营地铁隧道沿线围护桩提供施工参数。Based on the site test data, research was made on the impacts of the pile constructed by SMW method with different W/C ratios and drilling speeds on the displacement of deep soil. Results show that 1.2 W/C ratio and 50mm/min drilling speed are appropriate, and may be referred to for the construction of enclosure piles near the metro line tunnel in operation.
