Abstract: | Three shaking table model tests were conducted with a geometrical scale of 1:10 using a large-scale laminar shear box to investigate
the reinforcement effects of compacted gravel column-net composite foundation and cement fly-ash gravel (CFG) column-net composite
foundation on the saturated silty soil along the Beijing-Shanghai High Speed Railway. The research results indicate that the
increase in excess pore water pressure can be restrained effectively by the compacted gravel column-net composite foundation
to improve the anti-liquefaction ability of the ground, and that shear displacement of the ground can be reduced greatly by
the compacted gravel column-net and CFG column-net composite foundations to improve the capability of resisting shear displacement
of ground. Furthermore, the amplifying of response acceleration, induced by foundation liquefaction, and the settlement of
foundation and subgrade can be reduced greatly by the compacted gravel column-net and CFG column-net composite foundations
to improve the aseismatic property of the foundation and subgrade.
