摘要:
由于浅部断层带中的岩体比较软弱和破碎,所以成为应力降低带,而深部工程中断层带对地压分布的影响是一个有待深入研究的问题。为了了解和掌握深部地压分布规律,本文中通过结合某工程现场条件,在实际调研和岩石力学实验的基础上,建立了力学数值模型,分析了深部工程中断层带对深部地压分布的影响。结果表明,深部工程中断层的存在影响了地应力分布的连续性,在同一水平高程上,断层上盘的主应力大于断层下盘的主应力; 高地应力出现在断层上盘和矿层上盘的交叉区域。
Abstract:
As a key and difficulty point of the rock engineering research, deep rock engineering has a lot of questions to work out. Especially in field of energy and national-defense, it is very important for deep rock engineering to know and master the rule of ground stress distribution. Because the rock mass in shallow fault zone is weak and broken, it becomes stress drop zone. But it needs much research on deep fault-zone's influence on ground stress distribution. The paper which is combined engineering practice and based on investigation and test of rock mechanics, builds up mechanics numerical simulation model and analyses deep fault-zone's influence on stress distribution. It demonstrates that deep fault-zone breaks down the continuity of ground stress distribution, primary stress in heading wall of fault-zone is smaller than it in hanging wall and high ground stress is in cross district of fault-zone' hanging-wall and mentor's.
