Abstract
PURPOSE: To prevent the liquefaction of sandy ground at earthquack by providing a drainage consisting of a porous member and granular articles in the sandy ground and thereby controlling the rise of an excessive neutral stress therein.
CONSTITUTION: Based on an excessive neutral stress to take place in the ground 1 found in accordance with the magnitude (the size of shearing stress) of an earthquake estimated for the sandy ground 1 and in consideration of the size, importance etc. of a structure, the interval of the following drainage 2 to be laid is selected. The drainage 2 is constructed by filling the ground 1 with a member 3 of spongy or multifiber structure. In addition, a porous pipe body 4 with a bottom is also buried in the ground 1 and filled with large gravels 5 at need, thus the drainage 2 is formed.
