모래다짐말뚝(SCP)의 치환율과 혼합율에 따른 강도정수의 상관성에 관한 연구 

Study on the Relationship of Strength Parameters with SCP Replacement and Mixture Ratio 

[ 초 록 ]

When SCP (Sand Compaction Pile) is used in the improvement of soft ground, some problems like the difficulty of vertical construction and other construction difficulties due to the use of high pressure are encountered, There is a possibility that the strength parameters used in the design may be different with those obtained from the investigation of the quality variation with depth for the irregular, then the section may be not a sand pile but a combination of sand and clay. The mixture ratio concept is used, it is defined as the quantity of sand corresponding to the replacement ratio. Using this concept, the strength parameter relationship of the replacement and mixture ratio was determined. The use of these parameters in the design of SCP is most appropriate.
