Abstract
A method of construction on natural or artificial soils subject to liquefaction involves the provision of one or more permeable wells penetrating the soil supporting a structure, such that excess water pressures induced by cyclic loads on the structure can be relieved. Pumps can be used to maintain the water pressure in the wells lower than the natural water pressure in the surrounding soil. The wells may be filled with water-permeable material. Structures in accordance with the invention can be of various forms, wherein drainage may be through one or more dowels or through a cushion on the lower section of the structure or structures.
