Overview of monitoring methods for the settlement deformation of alluvium deposit
The settlement deformation of alluvium deposit can directly influence the operation of dam structures,making it an extremely important monitoring item in hydraulic engineering.The alluvium de-posit is buried under dam body,thus its settlement deformation is difficult to be measured during con-struction and operation periods.In this study,several existing monitoring methods are systematically summarized.The working principle and installation method of instrument are compared.And some engi-neering examples are employed to explore the merits,defects and applicability of each monitoring meth-od.Meanwhile,based on existing monitoring results,the settlement deformation laws of alluvium deposit of dam foundation are concluded.This study can provide reference for monitoring design and research on mechanical properties of alluvium deposit in similar projects.
