The results show that the air crossing pressure pulse magnitude of the container generated in the tunnel is 3.46 times that generated in open air when container flat wagon at the speed of 160 km/h passed by EMU moving at the same speed. Both the lateral force and overturning moment of the container train during the crossing induced in open air and tunnel are approximately proportional to the square of running speed of the passing train. The pressure of crossing side and uncrossing side for the container flat wagon is almost equal since the one-dimensional characteristic of pressure distributing induced in the tunnel is not faintish. Consequently, the value of the lateral force and overturning moment of the container train generated in open air is greater than that generated in the tunnel, about 1.1 times.

研究结果表明：集装箱平车以160 km/h的速度与动车组等速交会时，在隧道内会车时车载集装箱中部压力变化幅值是在明线会车时的3.46倍；在明线和隧道内会车时，集装箱列车受到的侧向力和侧滚力矩均与交会列车运行速度近似成平方关系；因隧道内压力分布一维特性较强，集装箱平车交会侧与非交会侧压力相差并不大，因此，在明线会车时集装箱平车受到的侧向力和侧滚力矩均比隧道会车时的大，大约是其1.1倍。

The shape of tunnel is gained by use of many processing ways to the initial images in the field. The quantity of overbreak and underbreak is gained by contrasting between the extracted shape and the designed shape. The same method is applied to other tunnel sections then the overbreak and underbreak quantity of a certain section or the total tunnel is gained so the problem about the evaluation of overbreak underbreak in the tunnel is solved quantitatively.

通过对野外摄取的隧洞图像进行一系列的处理得到隧洞的基本形状，然后与隧洞的设计形状对比分析，即可得到隧洞在该断面上的超欠挖方量，然后对其他断面采用同样的技术就可评价某一段或整个隧洞的超欠挖数量，这样就从定量的角度解决了以往工程中难以解决的超欠挖评价问题，为工程超欠挖的判断与决策提供合理依据。

The Shi zi mountain rock tunnel which connecting the Punan expressway and the Nanping city in Fujian province were taken as engineering background. Associating plentiful of field test data of vibration velocity with the finite element numerical simulation which based on MIDAS/GTS software, the blasting vibration behavior of the precedence tunnel in the Shi zi mountain rock tunnel was studied. For further, the effects that lining support systems with variation parameters, such as the length, the distance and the length of rockbolts, the spacing of steel braces, the thickness and reinforcement quantity of the secondary lining,,on the blasting vibration behavior of the precedence tunnel were systemlly discussed.
