Stability Analysis of Earthen Embankment of Kollong River, Near Raha, Nagaon, Assam
Abstract Stability of an earthen slope can be analyzed using circular slip circle method. In this method, an optimal search is carried out to find the most critical slip circle corresponding to the minimum factor of safety. For obtaining the factor of safety of the critical slip circle, information about the subsurface strata is necessary. Most of the time, the slip circle is considered as homogeneous in nature. In this study, heterogeneity of the bank material is considered in the stability analysis of a river bank. A field survey is initially conducted using Ground Penetrating Radar (GPR) to acquire information about the nature of the subsurface soil strata of the embankment. Information extracted from the GPR survey was verified using actual bore log data. Stability analysis of the embankment is then carried out using circular slip circle method. The methodology is applied for the river bank analysis of the river Kollong at Raha, Assam. The evaluation shows that the methodology is effective in studying the stability analysis of river banks.
