泛亚铁路高突泥涌水风险隧道地质灾害表现及对策
|
摘要
在建泛亚铁路通道玉磨铁路工程地质条件复杂,突泥涌水、软岩变形、高地热等地质灾害频发,对隧道施工和作业人身安全构成极大威胁,对全线建设工期产生较大影响。以新平隧道突泥涌水灾害为研究对象,针对性采取超前地质预防、动态设计、专业机械化配套等手段,并与专业施工队伍相结合,预防、避免灾害性伤亡事故发生,保障国家"一带一路"建设项目顺利推进。
The geological conditions of the Yuxi-Mohan railway of Trans-Asian railway under construction are complex with frequent geological disasters such as water and mud burst,soft rock deformation and high geothermal heat,posing a huge threat to tunnel construction and personal safety and imposing great impact on the construction period of the entire line.Taking the water and mud burst in Xinping tunnel as the study object,this paper,combining the role of professional construction team,takes targeted measures such as advanced geological prevention,dynamic design,and professional mechanization to prevent and avoid fatal accident,ensuring the smooth progress of China’s"Belt and Road"projects.
