摘　　要：隧道工程具有造价高、工期长、风险高、施工难度大等特点,隧道勘察成果质量直接影响到工程的造价和安全,若因隧道勘察不准导致后期施工设计变更增加造价将会非常麻烦,若未查明不良地质作用和地质灾害,还可能引发安全事故。随着建设工程质量要求的提高和设计变更越来越困难,受场地条件、工期等限制,市政隧道工程勘察面临着愈发严峻的考验。文中以某复杂地质条件下大断面隧道工程为研究对象,采用钻探、工程地质调绘、物探、原位测试等多种勘察方法综合研究,以期为类似工程提供借鉴。Tunnel engineering is characterized by its high cost,extended duration,significant risks,and challenges in construction.The quality of tunnel survey results directly impacts the cost and safety of the project.If the late construction design is changed and the cost is increased due to incorrect tunnel survey,it will be very troublesome.If the adverse geological effects and geological disasters are not found out,it may also lead to engineering safety accidents.With the improvement of the quality requirements of construction projects and the difficulty of design changes,the municipal tunnel engineering survey is facing more and more severe tests due to the restrictions of site conditions and construction period.This article focuses on a large-section tunnel project under complex geological conditions and employs various survey methods,including drilling,engineering geological surveying,geophysical exploration,and in-situ testing,to offer insights for similar projects.
