STABILIZATION OF POTENTIAL LIQUEFIABLE SAND DEPOSITS USING GRAVEL DRAINS. CLOSURE

The authors note that the application of the drainage principle for stabilizing potentially liquefiable sand deposits should only be used when it proves to be partically suitable and economical. It is noted that the collection and disposal of the water collected in the drains must be part of the design of any such installation but the nature of such a system will vary with each individual case. Simular the effect of head loss in the drains due to the rise in waterlevel will vary from case to case. The problem of more complex drainage systems involving the presence of a pipe and an external filter zone of finite permeability is also discussed. The anlaysis developed in the original paper may be extended to more general flow conditions and a general purpose, finite element program, GADFLEA, capable of analyzing cases of nonradial flow and with permeability and compressibility characteristics that vary with depth has been developed. This programs makes it a straightforward matter to analyze the effects of nonradial flow and drains that are not infinitely permeable.
