Fault information was obtained by analyzing residuals with fuzzy residual evaluation, which overcome a high rate of misinformation associated with the thresholdevaluation method.
Critical sealing threshold in each evaluation stage was established for evaluation on the fault sealing property, which may evaluate the key factors of the fault sealing property.
在每级评价中建立断层封堵性评价的临界封堵界限，可实现对于断层封堵性关键因素的评价。
