Seismic response of municipal solid waste landfills S. Singh Department of Civil Engineering, Santa Clara University, C/ara C4 ABSTRACT A brief but critical evaluation of the seismic response of Municipal solid Waste Landfills (MSWL) have been presented. Parametric studies on the dynamic response using range of values for shear modulus and damping characteristics of the refuse material were carried out. Results of seismic response analyses (for different levels of base motion) performed by the authors and other investigators are examined to evaluate the impact of stiffness and height of the refuse fill on the overall response. A strong influence by a moderate increase in dynamic strength (stiffness) properties on the response has been noted. Based on these analyses the influence of shear wave velocity is discussed. The importance of low and high frequency contents of the base motions is also addressed. Simplified procedures to estimate amplification of seismic ground motions by MS
