吹填区宕渣回填地基变形机理研究
Research on Deformation Mechanism of Slag Backfill Foundation in Reclamation Area
摘要
Abstract
In order to study the deformation mechanism of the foundation backfilled with slag in reclamation area,a reclamation area foundation slag filling project in Wenzhou,Zhejiang Province is taken as the research object.The numerical simulation and parameter sensitivity are adopted to be the research method.The foundation deformation phenomenon in the process of on-site slag backfilling is analyzed by PLAXIS software.The key influencing factors of the foundation deformation is found out by parameter sensitivity analysis.The research results show that the changes of elastic modulus,Poisson's ratio and groundwater level of soil have great influence on the deformation of foundation.While the changes of internal friction angle and cohesion of soil have little influence on the deformation of foundation.关键词
