摘　　要：挤土桩的挤土效应会引发较为严重的环境问题,对于深层搅拌桩可采取减缓成桩速率等4条措施进行防治;对于钻孔灌注桩可采取机械处理、化学处理、机械化学联合处理、重力沉淀处理等措施;防治桩基沉降引起地铁隧道位移的措施主要有加长工程桩、设置遮拦桩、跟踪注浆法等。The serious environmental problems can be induced by the soil-displacement effects of soil-displaced piles. Four prevention measures can he adopted for the deep mixing piles by reducing the forming pile rate. The measures of the mechanical treatment, the chemi- cal treatment, the combinative treatment of machinery and chemistry, and the gravity deposition treatment can be adopted for the bored cast- in-place piles. The prevention measures for the underground tunnel dis- placement caused by the pile settlement mainly include lengthened piles, setting shelter piles, following grouting method, etc.
