摘要
Land subsidence model is an important part in research of land subsidence. And meantime study of aquitard deformation model is an important part in research of land subsidence model. The author analyzed pore water type of deep depth aquitard and studied the deformation characters of the pore water type of deep depth aquitard, and understood the deformation mechanics of deep depth aquitard. Based on deformation mechanics analysis, non-Darcy flow was adopted to modify calculation model of land subsidence, and the authors put forward deformation model suggestion of deep depth aquitard.
