An Approach to the Treatment for Soft Clay Base by Using a Combination of Sand Cushion and Sand Drain

The present paper introduces the design and construction of a multistorey brick building on a marine sedimentary soft clay foundation by means of Combination of sand cushion and sand drain, with no load increment applied before the upper structure’s construction. The building, the construction of which began in the summer, 1979 and ended in the winter, 1981,is in good condition during the recent three years, no abnormal deformation being found. With its advantage of simplicity and economy the construction is an example for successful application of soft clay foundation treatment of this sort in the building construction.
