Profile of subgrade subsidence in Sorchen

Abstract

The highway along Sorchen have been imperiled to various mechanical damages posing tremendous problems to the road users. These damages of road and its sub-grade are contributed by number of factors both manmade and natural. This research focuses on identification of damaged subgrade and its causes to the measurable degree. The greater emphasis has been turned to the Geotechnical site investigation of the affected areas and quantification of the results for the benefit of the policy makers in future. The survey has been carried out to ensure the extend of subsidence of the road and shown in the graphical manner. Wenner’s 4 Spikes method ground resistivity test were also carried out to explore the sub surface of the affected subgrade. The research has also done on the possibilities of rigid slab supported by the pile foundation as the counter measures. The results obtained by the electrical resistivity test will be used to located the depth of pile foundation.
