RECOLLECTIONS FROM THE WROTH MEMORIAL SYMPOSIUM: PREDICTIVE SOIL MECHANICS

This article summarizes some of the interesting points which arose during the presentation of the papers at this Wroth Memorial Symposium. The constitutive modelling discussed falls into two main areas. The first was the use of a constitutive model to provide a framework for the interpretation of soil behaviour. The second was the formulation of new models to include specific features of the soil response. The importance of the link between good experimental data and the derivation of new or improved constitutive models was emphasised. Laboratory and in situ testing methods were also covered briefly. Short sections are devoted to the following in situ test methods: a) the pressuremeter; b) cone devices; and c) geophysical tests. Some methods used to predict a) vertical movements for ground above tunnels and b) horizontal movements adjacent to tunnels are also discussed. For the covering abstract see IRRD 859983.
