摘要：To identify the EZD formation and propagation mechanism,the humidity-stress-damage coupling model based on the environmental factor was established by introducing the humidity diffusion equation and the humidity weakening effect on rock characteristics.The EZD formation and propagation process was reproduced in numerical simulation,and the time-dependent de-formation and failure characteristics of surrounding rocks and their stress evolution process were analyzed.The results show that numerical result is in good agreement with that from field test.Humidity is an important factor that affects the EDZ formation, and this conclusion can not only explain the current doubts about EDZ but also provide some new ideas for the development of EDZ theory.
