Precast Concrete Sheetpile for the Stabilization of Road Embankment on Soft Ground Adjacent to River

Abstract:

Precast concrete sheetpile designed to restore and protect a road embankment, undergoing continuous settlement in soft ground condition in Jerlun and Kuala Sanglang in the state of Kedah, Malaysia is presented. The road built on soft ground has been in service for several years with some anticipated settlements. Major defects in the form of uneven settlements were spotted after few years of service. A survey was conducted and 5 spots along a 30m to 40m long stretch experiencing about 100mm settlements relative to the centerline of the road. Several attempts have been made to backfill and re-surface the affected areas but the road conditions did not last, posing danger to motorists. Investigations have revealed slip circles did occur at the affected areas with signs of lateral movements of earths towards the river. Precast concrete sheetpiles were designed to stabilize the road embankment to prevent further lateral movements of earth due to vehicular loads on the road. Analysis and design of the sheetpile system are presented. Construction aspects related to handling, installing and finishing works at site are highlighted.
