| Abstract: | Taking QingLinJing Tunnel of BoLuo-ShenZhen Expressway as the background,this paper has discussed application of conversion between three-step method and the ring heading excavation method with core soil remaining,in the construction,due to timely conversion of the construction method,not only the stability of surrounding rock has been guaranteed,but also the construction schedule has been appropriately accelerated,which can be used as references for the soft surrounding rock tunnel construction in the future. |
