Near-Surface Seismic Refraction Tomography; a case study for geotechnical application
Abstract: Usually, among geophysical techniques, seismic refraction methods are used to investigate near surface geology for engineering purposes. In these study physical parameters, longitudinal seismic wave velocities were used to characterize the shallow subsurface layers for geotechnical application. The physical response of subsurface materials varies as the structure, porosity, fluid saturation, composition and tie-up vary. These variations primarily viewed in the first arrival time of seismic waves. With the necessary steps, …

Probability of Liquefaction induced Ground Failure under the Earthquake Scenario in Kathmandu Valley
Abstract: Kathmandu valley is highly susceptible to liquefaction hazard due to the presence of liquefiable soil up to considerable depth, the presence of shallow ground water table and occurrence of earthquakes at regular intervals. Past studies have also shown the occurrence of liquefaction with examples of observed ejection of sand boil and formation of cracks throughout the valley during 1934 Nepal-Bihar earthquake. Events similar to these were also observed during recent …

Influence of wall friction on Active Earth Pressure in Model Test
Abstract: Earth pressure theories occupy a paramount position in the field of geotechnical engineering. The knowledge of active earth pressure under static condition is essential in designing a retaining wall as the damage to such retaining structures may lead to disastrous failure. A retaining wall helps in maintaining the ground surface at different elevations on either side of it. Without such a structure, the soil at higher elevation would tend to …

Strength Studies of Fly Ash Stabilized with Lime and Gypsum
Abstract: An experimental study was conducted to investigate the performance of a composite derived from stabilizing fly ash with lime and gypsum. The initial part of the study examines the effect of lime (4%, 8%, and 12% by mass of dry fly ash) on compaction (in terms of density/moisture relationship) and unconfined compressive strength (UCS) of fly ash. Further the effect of adding small amount of gypsum (1%) on strength was …
