Assessment of hydraulic heave for any deep excavations is very critical and appropriate suitable methods as well as good engineering practice shall be adopted for the assessment of hydraulic heave depending on the subsurface profile. Consideration of shear strength of cohesive soils plays an important role while estimation of hydraulic heave. This paper presents the assessment of hydraulic heave by analytical and finite element analysis for the deep excavation in layered soils.
