By using the second version of the Community Atmosphere Model (CAM2) of NCAR, the general circulations of the Earth's atmosphere were simulated under different obliquity condition. The results imply that three-cell circulation turn weak when the obliquity turn large except that the three-cell circulation in Northern Hemisphere in winter, Hadley circulation in Southern Hemisphere in spring and Hadley...
In the course of complex rock slope excavation, with the rescission of lateral stress constraint, the rock mass will produce unloading rebound deformation to the free face. With this course, the primary equilibrium stress state in slope mass is broken, and secondary stress adjustment occurs, which will adapt to the deformation state of continual development until new balance. The result is that the...
In this paper frost heave is simulated numerically by the coupled processes of heat conduction and moisture transport within frozen soil mass. A finite difference computational program developed by the first author is used to simulate frost heave of one-dimensional frozen soil under three different freezing modes including continuous, stepwise and continuous-intermissive mode. The results of simulation...
The 3-D RNG k - e numerical model of turbulence flow is built with FLUENT software. The mixture motions of water and sand, in the upper direction and side direction, are calculated. The results show that, the effect of jetting in upper direction is evident compare with the jetting in the side direction, under the condition of the same pressure and speed. It's easier to start suspending for the inside...
Existing calculation theories for soil pressure are all based on the two-dimensioned transverse vertical pressure developed on the culvert of the centerline of the highway, and are not suitable to the actual condition. Three-dimension pressure was discussed in this paper, and according to indoor experiments, the various conditions of the soil pressure around the culvert are found out along the longitudinal...
