| Abstract: | The N-sandstone distributed widely in Lanzhou area provides the only foundation stratum for tall and super-tall buildings or underground buildings,with the ever increasing scale of urban construction.The specific engineering capacities,including the composition of pellet,physical capacities,features of transmutation and intensity etc,have been systematically studied in this paper,in light of plentiful and detailed experimental data.Also,a superior method of defining the bearing strength of the N-sandstone is advanced. |

| Keywords: | N-sandstone parameter of mechanics property of engineering strength of foundation |
