APPLICATION OF ELASTOPLASTIC DAMAGE MODEL IN A LARGE SIZED UNDERGROUND POWER HOUSE
弹塑性损伤模型在某地下厂房工程中的应用

A 3-D elastoplastic damaged constitutive model for intermittent multi-joints rockmass is established. The model is applied to underground power house of a large sized hydroelectric station to carry out 3-D calculation of nonlinear finite element of elastoplastic damage under excavation and obtain some satisfactory results.
