CALCULATION OF THE TEMPORARY DIVERSION TUNNEL LININGS AT THE II LEVEL OF THE ROGUN HYDROELECTRIC STATION FOR SEISMIC LOADS

A method has been developed for calculating the linings of noncircular tunnels for seismic loads. The method is based on estimating the most unfavorable stress in each cross section of the lining among those possible in the presence of various combinations of the compressional and shear waves for any of the directions is the plane of the tunnel cross section. General solutions are detailed of 2 quasi-static plane contact problems of the theory of elasticity for a ring of arbitrary shape supporting a cut in a linear deformable medium with different deformation characteristics. The results of calculating several types of lining of the temporary diversion tunnel of the hydroelectric station are given. It is noted that consideration of the actual cross-sectional form of the structure and of the possible effect of dilational and shear waves along with comparession waves and of the entire range directions should promote an increase in the seismic stability of structures.
