The use of a DMT to monitor the stability of the slopes of a clay exploitation pit in the Boom clay in Belgium

In Belgium the Boom Clay is a well known overconsolidated clay formation. This Tertiary clay, with the same geological origin as the London Clay, is used for the fabrication of bricks, roofing tiles. In the article is described how the DMT can be used to evaluate the stability of slopes, to determine the risk of instability and how the cause of the failure directly could be related to the results of the DMT-measurement. The results of the tests before the period of instability, during the period of instability and after stabilization are discussed. The KD-value is a representative value to jud... Mehr ...
