| Abstract: | The paper takes railway rock slopes around Lueyang area of BaoCheng line for example.The probability pattern of rock mass was calculated and simulated with the aid of the Monte Carlo method.On the basis of the probability parameters,the rock solpe RQD in various directions was estimated and the concept of direction RQD was set.In result,the paper first tries to find out the application of direction RQD in the relationship of railway engineering activities and geological environment. |
