This paper uses a dedicated finite element software PLAXIS for geo-engineering,to further explore the rules of embankment settlement deformation under different heights,and discusses relationship between embankment height and road bed settlement deformation.

According to the field test data of the bridge-subgrade transition section in permafrost regions during 3 years after the construction,the ground temperature variation inside different locations of subgrade and the settlement deformation rules of subgrade basement and subgrade in different locations of the cross and the longitudinal section were analyzed.

Combined with practical engineering of Wenwu Road station,the author analyzes the causes of surrounding buildings settlement deformation in the process of subway construction,and proposes measures to control settlement and incline of the buildings,in order to ensure security of the buildings,which to offer some guidance for similar engineering constructions.

Based on numerical modeling combined with a practical engineering,the characteristics of consolidation settlement and deformation of the new and old road foundations are analyzed for an expressway widening project where the old road is unstable.

The settlement and deformation behavior of the soft clay subgrade are analyzed in detail before and after the opening to traffic.

Analysis on settlement of the discharge culvert under an earth dam in a plain-area

By centrifugal model experiments,settlement behavior of high filling embankments different dry density and water content conditions is researched,and it analyzed relation between settlement and dry density and water content,the impact of mixture ration on settlement under same dry density and water content conditions.

Based on the static equilibrium and deformation coordination condition of the big diameter extended-bottom pile,the formula for calculating the settlement of big diameter extended-bottom pile with the bearing platform effect,is put forward.
