不同岩性侧压系数分布规律的统计分析
|
摘要
通过收集我国大量的已有地应力实测资料,建立了岩浆岩、沉积岩和变质岩三大类岩石的平均水平主应力与垂直应力之比随埋深的散点分布图,并采用与霍克(E.Hoek)和布朗(E.T.Brown)同样的回归方法进行了回归分析,发现不同岩石间地应力的分布规律存在一定差异,其与岩石成因密切相关。为更进一步研究不同类岩石间地应力分布规律的差异,另统计分析了地应力与岩石弹性模量间的关系,结果发现岩石弹性模量对最大主应力影响大,而对中间和最小主应力影响小。该统计结果可深化对我国宏观地应力场的分布特性及地应力场影响因素的认识。
Through collecting a vast amount of the measured in-situ stress data in China and selecting the data which have less local impact, the scattered distribution diagrams of depth versus the average ratio of horizontal principal stress to the vertical stress,including three kinds of rock,i.e.magmatic rock,sedimentary rock and metamorphic rock,are established and the corresponding regression analysis is conducted adopting the same method given by E.Brown & E.T.Hoek.The research results show that the distribution characteristics of the three kinds of rocks are different,which are closely related to their formation cause of rock.For further studying the difference of distribution characteristics of the three kinds of rocks,the relation between in-situ stress and Young's modulus of rocks is established,and the results show that Young's modulus of rocks has the greatest impact on maximum principal stress,but has less impact on intermediate and minimum ones.The above statistic analysis results can provide useful references for the study of the macro stress field distribution and related influencing factors.
