Abstract

There are loss of lives and properties in many areas of the basin of the Nak-Dong river by the unusual weather and the localized heavy rain recently, and many difficulties of levee construction for prevention of disasters by acquisition of material and expensive transportation. In this research, The factors and causes which affect the strength through laboratory tests about the cemented sand that is mixed a few portland cement and sand of Nak-Dong river bed was researched closely. For providing the fundamental data which is needed in design and analysis of levee material, the compaction test and the standard triaxial compression test etc was conducted., analyzed compression strength and characteristic of stress-strain behavior in which the influence of cement content.

최근 이상기후 및 집중호우로 인해 낙동강유역의 많은 지역이 재산 및 인명손실을 크게 입고 있으며 제방축조 재료의 획득 및 운송비등의 증가로 인해 재해방지차원의 제방축조에 여러 가지 어려움을 겪고 있는 실정이다. 본 연구에서는 낙동강 하상의 모래를 이용하여 소량의 시멘트를 혼합한 시멘트혼합토에 대해 삼축압축실험을 통해 시멘트혼합율에 따른 특성을 규명하고자 한다. 이를 위하여 낙동강유역 하상 모래와 시멘트의 혼합율을 변화시키면서 실내시험을 실시하였다. 제체재료의 적합성 검토, 설계 및 해석에 필요한 기초자료를 제공하기위해 다짐시험 및 표준삼축압축시험을 실시하여 시멘트혼합율에 따른 강도, 변형에 따른 응력 및 거동특성 등을 분석하였다.
