The paper surveys advantage and disadvantage of the discrete model and the equivalent continuous model for 3D fractured rockmass. It seems therefore necessary to present a new model of seepage in order to remedy the two models above. By the cubic law the paper assumes that the water head on the surface between fractured elements and rock elements is continuous and the discharge on the connecting surface is discontinuous. It is possible to construct the generalized mixed model of fractured rockmass by combining the transmission matrix of rockblock elements with that of fractured elements. Compared to the double media model, it is unnecessary for the mixed odel to lead into every attached parameter, and every node of the seepage nets has only one water head. The mixed model would be useful to analyse the seepage flow in both continuous media and discontinuous rockmass. For example, in order to calculate the uplift pressure on the dam bottom, itis possible to divide the dam foundation into two: the one close to the dam bottom is discrete media; the other is continuum media. Finally, the water head, on the nodes creates with mixed model. By the discussions above, it is definite to say that the mixed model is simple and active. Moreover, for the problem of determination of free face which will arise in the analysis of seepage flow, the substructural primery flow method is presented to locate the free face. The method is a kind of fixed nets method, and it is simple. Finally, the paper calculates the seepage field of the rollercompacted concrete dam No.1 on the Niu-ri-creek and the results show that the mixed model has rationality and practical values.

In the paper, a elasto brittle damage model for rock mass in Laxiwa arch dam is presented. It is based on continuum media theory, and established on crack coalescence and elastic damage coupled with crack propagations in strain space. Based on this model, mechanical parameters and constitutive relations for elasto brittle behaviours were obtained from in situ tests in the dam site. The process of calculation is given in the paper.
