A study on Seepage Problems of Chamravattam Regulator Cum Bridge

Abstract

Chamravattam regulator cum bridge is the largest road bridge in Kerala, which was constructed in the form of a barrage to store the water in Bharathapuzha River. Within a short span of time Clfier construction, a large amount of seepage was observed beneath the structure. This project aims to study about the seepage problem of Chamravattam regulator cum bridge. The study was conducted with the help of 2D Finite element model, Geoslope. Using the model the quantity of seepage, exit gradient and uplift pressure distribution in different cross sections were found. The check/or resistance to the uplift and piping phenomenon was done in the cross-section where the seepage flow was found maximum. The obtained results were compared with the existing site conditions. The possible reasons for seepage problems were found.
