摘要
采用数值模拟方法,分析钻孔灌注桩施工对邻近苏州轨道交通一号线区间隧道产生的影响。结果表明:钻孔灌注桩在钻孔时对隧道结构的影响较小,浇注混凝土时对隧道结构的影响较大;桩基施工过程中,隧道的竖向变形较水平变形小。总体上,钻孔灌注桩施工对苏州轨道交通一号线区间隧道的影响较小。
This paper,by numerical simulation method,analyzed how bored pile construction affects the interval tunnel on adjacent Suzhou Rail Transit Line 1. The result shows that bored piles have little effect on the tunnel structure in drilling,while large effect in concrete casting; and during the construction of pile foundation,the vertical deformation of the tunnel is smaller than the horizontal deformation. In general,bored pile construction makes little effect on the interval tunnel on Suzhou Rail Transit Line 1.
