A Case Study on the Improvement of Rail Road Subgrade using Super Injection Grouting Method - Strength Increase in Marine Clay -

철도노반개량을 위한 고압분사 사례연구 - 해성점토지반에서의 강도증대효과를 중심으로-

Several soil improvement methods are applied to stabilize soft ground. But their improvement effects are known to be reduced in view of strength under poor conditions such as marine clay. The purpose of this paper is to investigate the strength increase effects of super injection grouting on the marine clay, A series of laboratory tests and chemical analysis tests has been peformed. Through this study, the causes of strength inferiority of treated soil was analyzed and soil improvement effects of grouted soil was presented.
