Abstract
The 1985 Michoacan earthquake caused extensive loss of life and severe damages. During the earthquake, the ground motions recorded at the soft clay sites were amplified by 8 to 50 times those at nearby rock sites. This study evaluates the factors influencing the seismic characteristics of the lakebed deposit in Mexico City. The essential components of response analysis are examined in both 1-D and 2-D soil systems. The amplification of ground motion can be evaluated in both 1-D and 2-D analyses. Results show that the soil property has much greater influence than the control motion on the surface ground motion. Meanwhile, the amplification of ground motion is more pronounced in the 2-D system than in 1-D system. The two-dimensional effect also results in greater amplification in the region close to the edge of lakebed deposits.
