| Abstract: | According to the in-site observed parameters and the mechanism of the anchor and cable combining support analyses,corresponding numerical analysis model by FLAC3D（Fast Lagrangian Analysis for Continuum）is set up to simulate the effect of the anchor and cable combining support in different rows and distances,therefore,a reasonable and economical distance of the anchors and the number of cables is obtained.The validity of the numerical simulation method is testified compared with the results of the field test.The results make guidance in the similar design of the roadway support. |
