A parameter study was performed to determine the effects of changes in constitutive properties on the results of calculations of MIXED COMPANY Event III. It was found that stiffening the underlying rock layers by means of the assumption of elastic behavior led to substantially improved agreement between the computational results and field measurements, particularly in the out-running region. Several explanations are discussed and recent experimental work relevant to the in situ behavior of the rock layers is discussed.
