英文摘要	The primary risk-resources of tunnel engineering is summed up, the risk index methods of risk assessment are analyzed and the time-failure probability is defined, which is the ratio of arc AB and arc OB. Arc AB is the distance between the intersection of the displacement time-curve and the threshold value of displacement and the displacement convergence value and arc OB is the distance between the action position of surrounding rock or supports and the convergence valve of displacement. The assessment method of risk losses is analyzed too.
