| چکیده | ||
| A new approach to modeling injecting domainhas been developed based on changing permeability coefficient in a certain form in theory of consolidation. The proposed model utilizes the variation of the coefficient of permeability with respect to the pore fluid pressure justifying flow characteristic below certain hydraulic gradients and void volume changes. A proposed numerical solution for heterogeneity of media with regards to the permeability coefficient also leads the results to a better grout extension solution. The potential of the proposed model is evaluated in predicting the propagation of grouting material due to a single injection bore hole. The general comparison indicates that this approach is capable of solving the injection boundary value problem. | ||
