贵广铁路东科岭隧道DK554+400~+456段处于全风化花岗岩、蚀变大理岩区接触带，隧道施工遭遇了长期的涌水涌砂等病害。结合东科岭隧道施工期间的涌水、涌砂概况及病害成因，治理采用堵排结合，即洞身全风化花岗岩段采用袖阀管注浆、仰拱底部蚀变大理岩部位采用钢管桩注浆加固，同时设置泄水洞等措施，成功解决了涌水涌砂加固治理难题。
貴廣鐵路東科嶺隧道DK554+400~+456段處于全風化花崗巖、蝕變大理巖區接觸帶，隧道施工遭遇瞭長期的湧水湧砂等病害。結閤東科嶺隧道施工期間的湧水、湧砂概況及病害成因，治理採用堵排結閤，即洞身全風化花崗巖段採用袖閥管註漿、仰拱底部蝕變大理巖部位採用鋼管樁註漿加固，同時設置洩水洞等措施，成功解決瞭湧水湧砂加固治理難題。

The section DK554+400 ~ +456 of Dongkeling tunnel on Guiyang-Guangzhou railway is located in the area with fully weathered granite and alteration marble. During the construction, sand-gushing and water-bursting often arise, not only increasing the difficulties but also posing long-term security risks. In view of the sand-gushing, water-bursting and other defects during the period of construction of the tunnel, it is effective to control sand-gushing and water-bursting through combination of plugging and drainage i. e. sleeve valve pipe grouting around the tunnel and steel pipe pile grouting at tunnel bottom, and setting-up drainage holes. The successful practices and technical parameters can be referred to similar project.
