深部岩体注气破裂的数值模拟

The Numerical Ssimulation of Cracking about a Deep Rock Mass Infused Gas

为减小二氧化碳的大气排放量,人类探索将其进行地质封存在注气过程中,岩体在气体压力作用下的开裂也受到人们的关注,针对气体压力作用下,岩体的破裂及裂纹扩展的问题,采用拉张破裂有限元软件,对岩体注气过程进行了数值模拟.

In order to reduce carbon dioxide emissions in the atmosphere, we explore its geological storage. With the gas injected, rock＇s cracking is concerned by people. For this issue, using the finite element software, it studies the rock＇s rupture and crack.
