  • Due to many cases of the liquefaction of sand-gravel soils induced by recent earthquakes, more and more attention is paid to the liquefaction of sand-gravel soils. Aiming at this problem, the small soil-box shaking table tests are performed using saturated sand-gravel soils with 4 kinds of gravel contents and 3 kinds of relative densities. In the process of analysis, firstly, the acceleration drift caused by the tilt of acceleration sensor is amended in order to obtain the rational results, and then the characteristics of the accelerations and dynamic pore water pressures (DPWP) are described. The results of the liquefaction resistance of the sand-gravel soil show that the gravel content and the relative density of the soil have obvious effects on the liquefaction resistance of sand-gravel soils. The more the gravel content and relative density, the greater the liquefaction resistances of the soils, and the greater the variances of liquefaction resistance. For similar relative density, the liquefaction resistances of saturated sand-gravel soils are obviously greater than those of saturated sand.
