Abstract }l.KpdRT2  
Rock mass is inhomogeneous in nature. Data for underground structure designs are mainly obtained from site investigations and >W8bWQ^fK  
tests, but they are very limited. For this reason, uncertainty exists in the process of constructing underground structures in a rock 8]My k>  
mass. In the design a tunnel support pattern, the most important parameters such as advance rate and excavation method must be k?^%hO>[  
determined optimally. However, it is difficult to determine these parameters quantitatively. In addition, if these parameters are deter- -"F0eV+y  
mined incorrectly, unexpected risk occurs such as the decrease in the tunnel stability or economic loss due to excessive amount of ]|,vCKju  
supports.  pz$_W  
In this study, a methodology to determine an optimal support pattern and advance rate for the design of a tunnel is introduced d2ohW|  
based on risk analysis. It can be confirmed quantitatively that the more the tunnel is supported, the higher the reliability index b![t6-f^z  
becomes and the more stable the tunnel is predicted to be. Also an optimal support pattern and advance rate can be determined hgj CXl  
quantitatively by performing a risk analysis considering the construction cost and the cost of losses that can occur due to the col- LL{t5(- _  
lapse of a tunnel. xC)7eQn/R

十分感谢楼主

我们宿舍一个人就用的这个外文翻译

    

    

关于隧道支护方面的风险分析，是报告还是小文章啊？

谢谢
