摘要

本文采用LAGAMINE有限元程序对考虑水力耦合的盆地大应变弹塑性变形进行了数值模拟。第一部分描述了岩石力学模型、流动模型以及它们之间的耦合。提出了体积有限元和界面有限元。第二部分致力于断层的建模，包括通过断层的水流。最后，将该程序应用于一个由沉降引起的盆地压缩。结果表明，根据断层的流体力学特性，断层可以被激活或不被激活。

Hydromechanical coupling and basin tectonic compression

This paper deals with the numerical modelling with the LAGAMINE finite element code of the large strain elastoplastic deformation of a basin taking into account the hydromechanical coupling. One describes the rock mechanics model, the flow model, and the coupling between them. Volume finite element are proposed as well as interface one. The second ones are devoted to the modelling of faults, including the water flow through the fault. Finally the code is applied to a basin compression induced by sedimentation. It is shown that depending on the fault hydromechanical properties, a fault can be activated or not.
