Abstract

Abstract

With MARC program, subroutine program of simulating vehicle moving load, contact iterative computing method and element life-death technique, the different mechanics states of contact and separation between slab and filling were simulated, on the basis of different foundation settlement modes, the coupling action of slab internal force and deformation was considered, the mechanics property and adaptability of slab were researched.The result shows that the flexural-tensile stress at the bottom of slab is not influenced when the length of slab separation section is less than 1.08 m, observably increases with the increase of the length, and the loading position of the maximum flexural-tensile stress at the bottom of slab is between the abutment and half of length of slab; the slab of length 6 m is suitable for treating the foundation that the settlement value is less than 3 cm, 8 m for 4 cm, 10 m for 5 cm.
