초록
There were huge damages of human beings and their properties in many areas of the basin of the Nak-Dong river by the unusual weather and the localized downpour recently. In this research against disasters, we want to know the special quality of strength of the cemented sand that is mixed with cement and poor-graded sand which is the materials of riverbed in the basin of the Nak-Dong river as levee's material. For that, we want to provide the fundamental data which need in the examination of adaptation of levee's material, design and analysis by investigating compressive strength by curing period and cement ratio, elastic modulus and stress by transformation from compaction test, CBR test, unconfined compression test, triaxial compression test as changing ratio of sand and cement from 2% to 8% at two points in the basin of the Nak-Dong river.
