Zusammenfassung:Based on a case of construction, HeiShilingTunnel in Zhangjiakou to Shijiazhuang Expressway in Hebei Province, the research on the supporting system at the poor geological rock was done with Three-dimension numeral simulating method. Then the stress field and displacement field induced by the nonlinear mechanical action of different constructional methods were studied, and the rational construction and supporting method were defined.
