摘要
青藏高原铁路长大隧道工程,因其特殊复杂的自然地理、地质构造、水文条件,施工中常遇大型断层破碎带与储水构造,易发生突水突泥情况,加之艰苦异常的作业环境,给工程施工带来极大风险。文章以拉(萨)林(芝)高原铁路藏噶隧道出口端突水突泥治理为例,简述了在处治青藏高原山区新断层构造带发生突水突泥过程中的原因分析、综合技术措施与经验,冀为类似工程的设计与施工提供有益借鉴。
Because of the natural geographical and geological and hydrological conditions of the complex,the Qinghai Tibet railway tunnel construction often encounter large fault fracture zones and water storage structures, prone to water and mud outburst,and hard and abnormal operation environment,which brings great risk to engineering construction.Taking the treatment of water inrush at the outlet of Zangga tunnel as an example,this thesis briefly described the cause analysis, comprehensive technical measures and experience in dealing with the process of water bursting and mud bursting in the new fault structural belt of the Qinghai Tibet Plateau,and provided a useful reference for the design and construction of similar projects.
