Research on Disease Treatment of Foundation Reinforced by DSM Piles in Deep Peat Soil Subgrade of Coastal Railway
摘要
Abstract
For problems concerning the subgrade cracking in the treatment of foundation reinforced by DSM piles in deep peat soil subgrade of a coastal railway project in Malaysia,through on-site investigation and supplementary stratigraphic survey,combined with construction monitoring results,theoretical analysis and numerical simulation are used to explore the mechanism of subgrade cracking.The secondary reinforcement measures and treatment scheme are put forward.By increasing the pile length of DSM pile composite foundation in the central area of subgrade to the bottom of soft soil layer,the overall post-construction settlement of foundation can meet the design requirements.关键词
