Abstract

This paper aims to analyze a calculation model based on the synthesis of the results of fracture mechanics and fluid mechanics theories, in order to study the effect of water pressure on crack propagation. The interaction between water pressure and crack propagation as well as the related factors such as stress intensity and crack trajectory are presented. The results show that the fluid pressure distribution can promote further crack propagation and this computation model is a very effective tool for simulating hydraulic fracture. In addition, the model will be of great significance in the design and evaluation of the stability of the fractured structures and affected by water pressure.
