현장스미어존 시험에 의한 지반교란특성 분석
Analysis of Ground Disturbance Characteristics by Field Smear Zones Test
초록
The installation of vertical drains by using a mandrel causes significant disturbance of the subsoil. Thus a smear zone may be developed with reduced permeability and increased compressibility. In this paper the extent of smear zone developing ground disturbance with the installation of mandrels are analysed by field smear zone test. The extent and the consolidation characteristics of smear zones around the mandrels is compared with the shape, the size of mandrel and penetration speed and is evaluated from the field smear test results. (circular, sqare, rectangle and oval type)
