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.
