Multi-field multi-scale numerical analysis method and system suitable for jointed rock mass

The invention discloses a multi-field multi-scale numerical analysis method and system suitable for jointed rock mass, and relates to the technical field of civil engineering, water conservancy and hydropower engineering and new energy engineering, and the method comprises the steps of macroscopic calculation framework establishment, microscale numerical model establishment, seepage stress coupling model establishment and numerical homogenization analysis. According to the method, a traditional model building and an integration process are converted into fine structure simulation and homogenization analysis under a periodic boundary condition, firstly, the small deformation assumption of the traditional model building is overcome, and a large deformation mechanical behavior of a material is allowed; and secondly, starting from the fine structure of the rock mass, the method does not need the traditional modeling process, and has general applicability to the rock mass with a complex structure. 本发明公开了一种适用于节理岩体的
