摘　　要：随着城镇化建设,工程活动常常导致既有隧道上部堆载,给隧道安全带来不利影响。文章以浙南某输水隧道为例,研究了既有浅基础输水隧道在地面新增堆载作用下的变形及保护措施。针对隧道周边环境、地层及堆载分布特点,对不同保护方案进行了分析,并利用有限元方法对隧道变形进行了模拟计算。计算结果表明:隧道保护方案可满足要求。该研究结果可为今后类似项目建设提供参考。With the construction of urbanization,engineering activities often caused the surface surcharge for the existing tunnel,which adversely affects the safety of the tunnel.Taking a water conveyance tunnel in southern Zhejiang as an example,this paper studies the deformation and protection measures of the existing water conveyance tunnel with shallow foundation under the secondary loading on the ground.According to the surrounding environment,stratum and surcharge distribution characteristics of the tunnel,different protection schemes are analyzed,and the tunnel deformation is simulated by finite element method.The calculation results show that protection scheme for the tunnel can meet the requirements,and the research results can provide reference for similar project construction in the future.
