节理岩体边坡损伤力学与FLAC-3D耦合分析

Coupling Analysis Between Damage Mechanics of Jointed Rockmass Slope And FLAC-3D

通过引入损伤张量模拟岩体的多裂隙性 ,将节理岩体视为含有损伤的连续介质 ,建立了节理岩体的损伤力学模型。应用FLAC - 3D内嵌FISH语言 ,探讨了与FLAC - 3D的数据交换方法 ,采用VisualBasic编制了损伤力学分析的计算机程序 ,实现了节理岩体损伤与FLAC - 3D的耦合分析 ,并应用于鞍钢眼前山铁矿南帮边坡的模拟分析中。

A damage mechanics model for jointed rockmass is established by the simulation of the multi-cleavage behaviour by introducing the damage tensor and by considering the jointed rockmass as continuous medium with damage. The data exchange technique with FLAC-3D is discussed by applying FISH Language that is inserted in FLAC-3D. The coupling analysis between the rock mass damage and FLAC-3D is realized by the computer program for damage mechanics analysis set up by Visual Basic, which is applied in the simulation analysis of the south slope of Yanqianshan Iron Mine, An steel.
