COUNTERMEASURE CONSTRUCTION METHOD AGAINST GROUND LIQUEFACTION
PROBLEM TO BE SOLVED: To provide a countermeasure construction method against ground liquefaction that reduces construction costs and curtails construction period, to be applied to an outdoor facility ground in a site of a condominium, an office building or the like, and a ground with a private house or other light-weight structure.SOLUTION: In a countermeasure construction method against ground liquefaction, a plurality of gravel drains 21 that uses a crushed stone and gravel is laid in a ground at a prescribed interval. A strength retaining ground 22 is formed by laying the plurality of gravel drains 21 in the ground, the strength retaining ground suppressing rise in water pressure around the gravel drains 21 at a time of earthquake and retaining a prescribed ground strength. Then, a surface layer slab 23 is laid over the strength retaining ground 22 around the plurality of gravel drains 21, the surface layer slab 23 being laid throughout an area of the ground to be provided with the countermeasure.SELECTED DRAWING: Figure 3
【課題】マンションやオフィスビル等の敷地における外構部の地盤、あるいは戸建住宅等の軽微な建物の地盤の液状化対策として、工事の費用を安くすることができ、その工事の期間も短縮することのできる地盤の液状化対策工法を提供する。【解決手段】砕石、礫を用いたグラベルドレーン２１を地盤中に所定の間隔で複数設置し、このグラベルドレーン２１を地盤中に複数設置することによって、グラベルドレーン２１の周囲に地震時に水圧の上昇が抑止されて所定の地盤強度を保つようになる強度保持地盤２２を形成し、この複数のグラベルドレーン２１の周囲の強度保持地盤２２の上に表層版２３を掛け渡すようにし、この表層版２３を対象地盤範囲全域にわたって設置するようにした地盤の液状化対策工法である。【選択図】図３
