摘要
以合肥轨道交通4号线天水路站-翠柏路站区间隧道为工程背景,采用数值模拟与现场监测的综合研究方法,探究小半径曲线隧道施工中不同地层损失率对地表沉降变化的影响。结果表明:超挖量越大,即地层损失率越高,所造成的地表沉降越大,变化速率也越快。
Taking the interval tunnel between Tianshui Road Station and Cuibai Road Station of rail transit line 4 in Hefei as the engineering background,this paper uses numerical simulation and field monitoring to explore the influence of different formation loss rates on ground settlement.The results show that the larger the overbreak volumes are,that is,the higher ground loss ratio,the greater the ground settlement and the faster the change rate.
