Effects of soil layer construction on peak accelerations of ground motions

BO Jing-shan ,LI Xiu-ling, LIU Hong-shuai ( Institute of Engineering Mechanics, CSB, Harbin 150080, China; Dalian University of Technology, Dalian 116024, China)  
In this paper, based on hundreds of actual engineering site profiles, the authors select and build several significant site profiles, which include the thickness of overlaying layer, the depth and thickness of soft soil layer at site. The ground peak accelerations of different soil layer constructions are calculated under three different intensity earthquake inputs through the equivalent linearization and wave propagation method for the earthquake response analysis of soil layers. The effect of the thickness of overlaying layer, the depth and thickness of the soft soil layer at site is analyzed, and some conclusions with realistic significance are arawn.
