실내약액주입시험을 통한 제주도 화산쇄설물의 지반보강에 대한 연구

Abstract

The excellent injection effect and the excellent strength of injection material at the same time and the selection of proper material for the permanent waterproof and reinforcement and the injection condition, etc., have been investigated through the experiment in case various kinds of ground reinforcement method including the chemical grouting method are implemented in public works becoming bigger recently in Jeju scoria in this study. The kind of injection material has been selected through the uniaxial compression test of injection material as the chamber test. An experiment was performed with model ground made of scoria, the injection performance of selected material has been identified through the evaluation test of injection range using the decision test of injection amount and the calibration chamber test. As a result of test, it has been analyzed that MSG appeared to have the excellent strength, durability and injection performance all compared with the ordinary cement, this result is judged to be possible as the ancillary data of design at time of design and construction with the chemical grouting method in the future.
