LIQUEFACTION RESISTANT STRUCTURE OF GROUND

摘要

<P>PROBLEM TO BE SOLVED: To provide a liquefaction resistant structure of the ground reducing a construction cost and a construction period compared with conventional ones. Ž<P>SOLUTION: A plurality of soil improving bodies of hollow cylinder shape constructed in the ground by a deep mixing method are arranged at spaces, and the ground within a frame of the soil improving bodies and the ground held between the adjacent soil improving bodies are improved. The soil improving bodies are arranged in n-rows and m-columns in a plane (both n and m are integers of 2 or more) or arranged zigzag in a plane. The soil improving body is of angular cylinder shape with a polygonal cross section or of cylinder shape with a circular cross section. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
