摘　　要：首先对隧道初始地应力以及目前的获取方法做出概况性的阐述,同时,以某隧道工程为实例,通过有限元数值模拟的方法,结合岩体自重、构造应力及河谷下切等多种影响因素,对初始地应力进行了反演分析,以使所求应力值在测点的计算值和实测值达到较好的拟合。This paper firstly introduce the initial ground stress of the rock masses and the methods how to get the stress at present. Then take a tunnel project as instance, with the virtue of finite dement method, considering the effect of the gravity, tectogenesis and the cut of river, analysed the initial earth stress of the tunnel region, to make the calculated value and the measured value of the obtained stress value in the measuring points better fitted.
