地下工程中岩移的断层效应探讨

STUDY ON STRATA DISPLACEMENT UNDER FAULT EFFECT IN UNDERGROUND ENGINEERING

应用优势面理论对地下工程开挖引起岩移的断层效应进行了探讨。通过先确定好一些优势指标,用优势指标法能找出断层网中哪些断层易受开挖影响而产生特殊的岩移现象,并预测其强烈程度,最后,基于优势面理论对岩移的优势断层效应的机制进行了分析。

The fault effect of strata displacement in underground engineering is studied. Through some preferred index,the preferred fault can be determined and the intensity of special strata displacement is forecasted by preferred index method. Finally,the cause of preferred fault effect of strata displacement is analyzed with preferred plane theory .
