STUDY ON EVOLUTION LAWS OF ZONAL DISINTEGRATION IN DEEP ROCK MASS AROUND PARALLEL TUNNELS
Under the influence of the so called Three high and one disturbance, namely the high geostress. high ground temperature, high karst hydraulic pressure, and intense mining disturbance, the engineering response of deep rock mass shows some new characteristic scientific phenomena. In comparison with responses of the shallow rock engineering, these new characteristic scientific phenomena have distinctive features, and cant be explained by traditional continuum mechanics satisfactorily, such as the phenomena of zonal disintegration. Based on this background, the results of numerical tests on mechanism and evolution laws of zonal fracture are put forward with RFPA. The phenomena and laws of zonal fracturing are briefly introduced, which has great theoretical and practical significance to deep rock engineering in China.
