由钻孔应力(应变)观测中的元件测值推断测区的附加主应力比值和方向
INFERRING THE RATIOS AND DIRECTIONS OF THE ADDITIONAL PRINCIPAL STRESS IN THE OBSERVING REGION FROM THE ANALYSIS OF THE OBSERVED VALUES OF THE ELEMENTS IN DRILL STRESS (STRAIN) OBSERVATIONS
【摘要】 本文讨论了在钻孔应力(应变)相对观测中,互成45°夹角元件测值间的关系,以及利用其测值推断测区附加应力状态的方法。
【Abstract】 It is discussed the relations between the measuring values of 45° angles of the elements of drill stress ( strain)relative observations,as well as the method of how to infer the additional stress conditions from the observed values of the observing region.
