Numerical modelling of soft clay treatment by drainage consolidation with sand wick explosive vibration and its verification with in-situ experiments;

By analyzing the settlement observed data in construction and running period of Jie-Pu Expressway,it shows that sand wick is reasonable and necessary for treating rotten wood and silt mixed layer.

This paper describes the application of sand wick stacking load and consolidated drained technique with the technique which earthwork material is sitted in road embankment and the "flag-wheel-addition" technique of fillingl to soft soil foundation in West Line of Guangzhu highway.
