Peat, with its complex nature, presents challenges in construction due to its low strength, high compressibility and highly nonlinear dynamic response. Infrastructure failures from static and seismic loads on peat emphasize the need for a thorough evaluation, particularly in data-limited regions like northeastern (NE) part of India. In this context, present study focuses on peat deposits available across Silchar, a rapidly developing city in the NE region of India in the state of Assam. Both in situ (geophysical and geotechnical) and laboratory (physical, microstructural, mineralogical, static and dynamic) tests were carried out to assess the response of peat under static and dynamic loadings. In the preliminary phase, in situ tests in the form of electrical resistivity (ER) and multi-channel analysis of surface waves (MASW), along with geotechnical tests like standard penetration test (SPT), were conducted to evaluate the lithological profile by evaluating resistivity and shear wave velocity (Vs). Field investigation was subsequently followed by experimental investigation where static parameters like shear strength and compressibility were evaluated by unconfined compression and oedometer tests respectively. As far as dynamic parameters are concerned, parameters in the form of shear modulus (G), modulus reduction (G/Gmax) and damping ratio (ξ) were evaluated in the range of low to high strain by resonant column (RC) and cyclic triaxial (CTX) tests respectively. In addition, ground response analysis (GRA) studies were also performed from parameters evaluated from experimental results to assess dynamic parameters in the form of peak ground acceleration (PGA), peak ground displacement (PGD), shear stress and strain incorporating site specific localized ground motions. Further, in order to evaluate the complex behavior at a micro scale, microstructural and mineralogical tests by field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDS) were also performed. Thus, present study emphasizes seismic design importance in peat-rich areas, serving as blue print by offering global engineering insights.
