Abstract

Liquefaction-induced lateral spreading has imposed damages to structures during past earthquakes. This paper presents experimental results of a series of 1-g shaking table tests on models reinforced with gravel and geosynthetics subjected to liquefaction-induced lateral spreading. Firstly, observations linked with the mechanism of lateral spreading based on the test without remedial measures are presented, followed by the results based on the test with remedial techniques by using gravel only and then gravel combined with geosynthetics as well. Furthermore, in order to obtain the additional results from the use of gravel and geosynthetics, further tests were done by varying the position of the geosynthetics in the gravel, which were at the bottom, in the middle, and at the top of the gravel layer. General test results including time- histories of accelerations, pore water pressures and displacements are presented and discussed in this paper. The results indicated that by applying the proposed mitigation measures, the seismic performance of the soil models can be improved by reducing lateral ground displacement, which best results obtained from soils reinforced with geosynthetics at the bottom and in the middle of the gra
