2.
The comparison of varying features of ground subsidence, plastic zone in surrounding soil and roof settlement of tunnel lining induced by construction of the large span exit between the two tunneling methods has been carried out.
对渝怀铁路彭水隧道出口段大跨度隧道 ,采用中壁法和下导坑超前台阶法两种不同施工方法开挖过程的二维有限元计算 ,对比分析了两种开挖方式下引起的地层沉降、隧道围岩塑性区、隧道衬砌内力以及拱顶下沉的变化特点 ,结果得出采用下导坑超前台阶法施工要比中壁法安全 ,因此该大垮度隧道宜采用下导坑超前台阶法施工。
