COUNTERMEASURE METHOD FOR GROUND SUBSIDENCE

摘要

<P>PROBLEM TO BE SOLVED: To provide a countermeasure method for ground subsidence which enables simple inexpensive construction and prevents a step from being formed on a road even when ground subsidence is caused at the ground around a workpiece. Ž<P>SOLUTION: The countermeasure method for ground subsidence carries out ground improvement 2 to gradually reduce the depth of a ground improvement part as it is separated from an existing workpiece 1 relative to the ground A around the existing workpiece 1. The ground improvement 2 is carried out within a range of a distance L which is calculated by dividing an estimated subsidence amount comprising a total amount of a subsidence amount due to liquefaction of a saturated soil layer and a subsidence amount due to shaking of an unsaturated soil layer by a travelable inclination.
