A STUDY OF THE COUNTERMEASURES FOR THE RESIDENTIAL GROUND SETTLEMENT BY THE EMBANKMENT IN SOFT GROUND

Abstract

The paper proposes the cement deep mixing method (CDM method) as a measure for the settlement control after comparing predicted and monitored settlements at a test embankment, and confirming effectiveness of both settlement prediction and CDM to control the settlements.
The paper newly proposes an optimum design chart relating the depth of the ground improvement, the width of the improvement zone, strength of improved ground, and angles of inclinations of the houses. The paper also proposes buffer consisting of a series of boreholes to control horizontal ground movement during CDM construction, and discusses its effectiveness.
