This method is a new counter measure system for sand liquefaction. The principal purpose of this method is based on promoting drainage. The slender polyethylene pipes used in this type of drainage are 5 to 10 centimeters in diameters with many small holes, in the body of the pipe. These pipes burned into the ground at intervals of 60 to 150 centimeters, surrounding the foundation of structures.
When the excess pore water pressure builds up during earthquakes, pore water flows into the pipes. As a result, build-up of excess pore water pressure can be reduced. In order to investigate the effectiveness of this method, two laboratory tests and three field tests were performed. The result shows that this method is applicable for preventing sand liquefaction in practice.
