3车道连拱隧道施工引起围岩位移变化的数值模拟

为研究三导洞施工对大跨度3车道连拱隧道围岩位移的影响,对某高速公路3车道连拱隧道施工进行实态建模,采用可以准确模拟岩土材料塑性屈服流动的有限差分法对施工过程进行弹塑性数值模拟,得出大跨度3车道连拱隧道开挖过程中周围地层位移的发展规律。     

Convective Heat Transfer Characteristics of the Elliptic Cylinder with Axis Ratio 4：1 in Crossflow

The heat transfer features around the elliptic cylinder of axis ratio 4：1 in crossflow were investigated experimentally within a wide range of Reynolds number. By means of heat-mass transfer analogy and the naphthalene sublimation technique, the local heat transfer distribution and the mean heat transfer coefficient are clarified.The result shows that the mean heat transfer coefficient is higher than that of a circular cylinder in most Reynolds number range regarded, and this superiority turns to be more significant with the increase of flow speed. Moreover, the effect of axis ratio on mean heat transfer coefficient was investigated tentatively. The oil-lampblack technique was employed to enable visualization of the flow pattern around the cylinder and on the cylinder wall.
