中文摘要:
      断层破碎带具有岩体碎裂、孔隙比大、可能涌水涌砂等特点,在此地质条件下施工需要确保隧道开挖安全进行。新建怀化至衡阳铁路线中的岩鹰鞍隧道富水断层破碎带施工,采用三台阶四步开挖施工工法,通过超前地质预报与超前帷幕注浆预加固措施,采取双层初期支护,实现了隧道的安全贯通。
英文摘要:
      Fault fractured zones have the characteristics of rock fragmentation, great pore ratios and possible water and sand gushing. When construction is performed under those poor geological conditions, the safe tunneling construction has to be ensured. In the process of the construction of the Yanying'an Tunnel of the newly built Huaihua Hengyang Railway, which is located in a rich watered fault fractured zone, the three bench and four step excavation construction method has to be adopted. Through the advanced geological forecasting and the pre consolidating measure of advanced curtain grouting, and upon the basis of adopting the double layer initial support, the safe penetration of the whole tunnel is realized.
