Performance Evaluation of Earthen Embankment Underlain by Marine Clay Deposit with Ground Improvement Techniques—A Case Study of Mangaluru Region, Karnataka
Marine clay is a natural soft soil deposit found in abundance in coastal areas. This soil is characterized by poor engineering properties with low shear strength. As, marine clay has high plasticity and compressibility, construction of embankment over marine clay is challenging as they undergo excessive settlement and also witness stability problems. In this study, numerical analysis of earthen embankment over marine clay deposit is analyzed using Plaxis 2D tool. The soil is obtained from Mangalore district, Karnataka, and tested to obtain engineering properties. The main objective of the study is to find the extent of settlement and amount of deformation that might occur if embankment is built on marine clay deposit of the adjoining area. The maximum settlement occurred due to prolonged induced loading and stability of embankment is being analyzed. The study aims to analyze the behavior of earthen embankment, factors governing safe construction of embankment, and properties of marine clay. The study is being extended to analyze the behavior of earthen embankment with different remedial measures to mitigate the upcoming geotechnical stability problems with the installation of basal reinforcement layer, stone columns, and sand columns. The results are recorded in the form of horizontal and vertical deformations, total and effective stress, total and Cartesian strains. Thus, for the earthen embankment, allowable settlement and enhanced performance of marine clay sub-soil after ground improvement are numerically analyzed for the economy, safety, and stability aspects.
