Title: Liquefaction countermeasure ground
Inventor: MIZOGUCHI KYOKO
IPC: E02D27/34
Filed: 2019-09-27
Abstract: To provide a liquefaction countermeasure ground that allows the liquefaction of the ground caused by an earthquake and like to be suppressed in a simple configuration at low cost.SOLUTION: A vibration absorbing material 10 for absorbing vibration is mixed in a liquefaction layer 4 easily liquefied by vibration of an earthquake. The vibration absorbing material 10 is made of resin or rubber elastic material. Thereby, on an application of repeated vibration due to the earthquake, a part of vibration energy is absorbed with the vibration absorbing material 10 to mitigate the vibration. As a consequence, an increase of water pressure in gaps between sand grains in the liquefaction layer 4 is suppressed, which suppresses a deterioration in the bonding of sand grains caused by shear stress and friction. Thus, it is possible to suppress the subsidence of a building 2 caused by lost strength of the ground 1 liquefied due to settled sand grains.SELECTED DRAWING: Figure 1
