Using the program the wind fields around several buildings with different body shapes are analyzed . the final results of grid division and refinement are presented . the final wind velocities around the building and wind pressures on the building surface are obtained and also compared with those from the wind runnel test 采用計算程序對幾種不同體型建筑物的流動風場進行了模擬計算,給出了計算區域的網格剖分和加密結果,獲得了離散后的流場的風速和風壓模擬結果,并與風洞試驗結果進行了比較。

Usually long span roofs can be categorized as closed and open type regarding whether their inner surface suffers from wind directly or not . according to these different types , different ways of wind runnel test are given to obtain the wind pressures on long span roofs . and the characteristic of wind pressure distribution on each type of long span roofs is discussed with regard to the roof shapes 首先,對于大跨度屋蓋結構的表面風壓,本文提供了一套具體的分析思路,分四周封閉體型和整體敞開體型對大跨度屋蓋結構進行風洞試驗方法和風壓分布規律的分析,并討論了大跨度屋蓋結構的干擾效應和抑風措施。

Using a vortex - flow drop shaft to convey water from a high level to a diversion runnel under the condition of high water - head and large discharge is a new kind of technology in the scheme of reusing a diversion tunnel as a discharge tunnel 近年來,為解決高水頭、大流量導流洞改建泄洪洞的技術難題,旋流式豎井泄洪洞逐漸成為研究熱點之一。但迄今為止,該技術尚未得到推廣應用,其主要原因在于人們對豎井螺旋水流運動特征缺乏足夠的了解和深入的研究。

Finally we set up three - dimensional space model to simulate the space effect during tunnel construction , analyze the transaction between the left runnel and the right tunnel , and also analyze the deformation and stability of mid - partition 最后建立了三維空間模型,對連拱隧道開挖時的空間效應、左右洞的相互影響,以及中隔墻的變形和穩定性進行了模擬分析。

The key technique of this project is the design and construction of four deep - lying long runnels . their length , diameter and maximum bury - depth are 18 km , llm , 2500 m 這一工程的關鍵技術是四條長達18公里、開挖洞徑11米、最大埋深2500米左右深埋長隧洞的設計和施工。

( 8 ) as for the runnel which is located at a karst zone with a high water level , external water load is the main one , and rock pressure is secondary 門)在巖溶富水區隧道地下水水頭較大時,外水荷載是襯砌結構的主要荷載,圍巖壓力相對來說是次要荷載。

Ancient girders creak and groan , ropes tighten and then a trickle of oil oozes down a stone runnel into a used petrol can 譯文:古木大梁壓得嘎吱作響,纜索開始繃緊,接著便見一滴滴的油沿著一條石槽流入一只廢舊汽油桶里。

But to deep - lying diversion runnel , there are a lot of problems to be resolved not only hi design theory but also in techniques 然而對深埋引水隧洞,無論是設計計算理論,還是施工建設技術,都處在探索階段。

They used waterproof cement to prevent water from seeping through the roof of the runnel 他們用防水水泥來防止水從屋頂的排水通道里滲透。
