| Abstract: | There are two types of seepage media in the fractured rock mass, the main seepage part is the seepages through the discontinuities. It is very difficult to simulate the seepage characteristics of the intersected fractures in the network like in the fractured rock mass according to the conventional method. Therefore, the basic idea to simulate the seepage law of the intersected fractures is to get the two dimensional fractures network from three-dimensional random discontinuities numerical network model, applying meshless method based on the least-squares procedure which is moving approximately least-squares procedure, the test calculation is carried out by the program which is self written, a satisfying result is simulated, the feasibility of simulating the seepage law of intersected fractures by meshless method is proved. |
