摘要
Abstract
Taking stop line engineering of Guangzhou Metro Station for example,through similar indoor large-scale model test,combined with numerical simulation,the convergence of tunnel perimeter,displacement response of ground surface and stratum during excavation of large-section shallow-buried metro by benching tunneling method are studied.The results show that through the corresponding auxiliary construction method and reasonable construction procedures,benching tunneling method can effectively control convergence of tunnel perimeter and ground surface settlement caused by upper bench excavation,and thus reduces the impact on ambient environment to ensure rapid and safe construction.关键词
