谷竹高速公路文峰隧道塌方处理措施

Treatment Measures of Landslide of Wenfeng Tunnel of Guzhu Freeway

结合工程地质实际,分析了谷(城)至竹(山)高速公路文峰隧道施工过程中塌方的原因,提出对破碎岩体采取临时支撑、注浆、泵送混凝土等措施,使其固结稳定以保证隧道的施工安全。实践表明,加固措施安全可行。

Combined with practical engineering geology, t the process of construction of Wenfeng tunnel of Guzhu broken rock including supporting, pouring and pumping and stable to ensure the safety in tunnel construction. measures are safe and feasible. he paper analyzes the landslide causes during highway, and put forward the measures on concrete, which can make it strengthening The practice shows that the reinforcement
