模拟试验

The model incorporated with the aerodynamical urban canopy scheme is better to simulate the wind field on the urban areas.The conclusions are drawn by the comparisons between the simulation results of the building drag scheme and the aerodynamical urban canopy scheme in a real town: the simulated wind speed with the aerodynamical canopy scheme on the town areas is always lower than that on the surrounding rural areas, but that with the other scheme is not so.

分别采用建筑物拖曳法与建筑物动力冠层方案对一个实际小规模城市进行模拟试验，分析表明引入建筑物动力冠层方案可以模拟出小规模城市地区水平风速偏低的现象；还可以模拟出城市地区建筑物动力作用对湍流活动的影响；对湍流动能模拟结果表明比较符合实际分布情形。

Thissubject exerts the experiment method of analogue modeling, and we take geologic mining condition of the Xin Zhi Colliery of Huo Zhou Mineral Bureau in Shang Xi province as the physical model of background design. The experiment is divided into two phases, the first phase simulates the course of mining subsidence, we study rule of movement transmogrification of mining terrane. In the second phase, after the mining subsidence is gradually stabilization, we bring into bear different load in the different location of subsiding basin, and we study ground stability with goaf.
