Soil Settlement Analysis from Field Monitoring Data and its Simulation at Kanchpur Bridge

Abstract

The study and measurement of the settlement is a concern for any Geotech engineer. For the serviceability of subgrade projects, the prediction of embankment settlement is a critically important issue. We have to calculate settlement especially differential settlement to ensure the design grade of embankment. This study includes the project Embankment Settlement of Kanchpur bridge. The embankment should be placed considering and risk associated with surcharge loads. In this thesis, finite element analysis using PLAXIS-2D has been used for the analysis of finite elements. Hardening Soil Model and Soft Soil Model have been used in this simulation as a constitutive model. Various field tests have been done by ProSoil from where soil parameters have been determined. Using these parameters, settlement of embankment in soft soil has been estimated. Geogrid has been used for the improvement of the soil along with the determination of the settlement through conventional method.
