LINEAR DYNAMIC ANALYSIS ON ROCK-MEDIA OF OLD TUNNEL AFFECTED BY BLASTING VIBRATION OF NEW TUNNEL WITH SMALL LINE-CLEARANCE
Yang Shengquan(The Mining and Metallurgy Institute of Changsha,Changsha 410012)
In this paper,linear dynamic analysis on the circle of old tunnel and rockmedia is proceeded on the condition that the lineclearance of two tunnels is small,according to the result of the blasting vibration test and measure of old tunnel,combined with the calculation of the stress and displacement etc.of rockmedia affected by digging of new tunnel.At the same time,it is proposed some problems which should be paied attention to in similar engineering.
