ANALYSIS ON SISMIC RISK OF THE CONVEYANCE WATER TUNNEL ENGINEERING IN SHENZHEN

With reference to the existing determination and evaluation about seismic intensity in Shenzhen region,according to the analysis of seismogeology and the calculation of exceeding probability,and in consideration of importance of the conveyance water tunnel engineering,the nearly east-west line between ZD₃ and ZD₃ of the tunnel is taken as the zonation boundary of seismic intensity,north of which belongs to an intensity of Ⅵ and south an intensity of Ⅶ.
