中文拼音 [gānggǒngdǐng]
鋼拱頂
英文
steel dome-
Tensile stress field would appear in the proximity of arched vault after excavation, slacking of surrounding rock and subsequent dropping of blocks of rock from such area would possibly occur at any time in the context of extra - shallow depth. so i - steel arched support must be erected to provide against possible block dropping and be integrated into a ring with that of pilot tunnels on both sides
拱頂在核心土開挖后，在一定范圍內出現拉應力區，在超淺埋情況下極容易掉塊和發生圍巖松馳，因此核心土必須邊開挖邊架設工字鋼拱架，使之與左右導洞拱頂工字鋼形成整體。Presented in this thesis is a model test of the arch ribs segment with concrete filled steel tube ( cfst ) of maocaojie bridge, which is located in the yiyang of the hunan province and provides the engineering base for the test
本文以湖南省益陽茅草街大橋為工程背景，進行了茅草街大橋主拱圈鋼管混凝土拱肋拱頂1 ： 5節段模型試驗。During the construction of the concrete lining for the diversion tunnel of xiaowan hydropower station, the concrete linings for the sides and the crown of the tunnel are simultaneously placed by the integral steel shuttering trolley with the greatly shortened construction progress
摘要小灣水電站工程在導流洞混凝土襯砌施工中，邊頂拱混凝土採用整體式鋼模臺車一次襯砌成形，大幅提高了施工進度。On the basis of simplified calculation model presented by doctor wangxiaoping, some finite element models are set up. by finite element model program sap93, an analysis of static models of 18m - span and 30m - span w666 acmr in different supporting conditions is made. also a study on the relation between definite support displacement, which reflect variational stiffness of substructure represented by steel column or reinforced concrete column, and load - carrying capacity mechanical performance is made too
本文以w666金屬拱型波紋屋頂為研究對象，沿用王小平博士的簡化計算模型，對18m 、 30m跨波紋拱兩端不同支座形式（鉸支、固支和彈性支座）分別利用有限元計算程序sap93進行計算分析，研究波紋拱在不同跨度，不同支座形式下，不同外荷載作用時對該結構受力性能及穩定承載力的影響，同時分析下部支承鋼柱、鋼筋混凝土柱的剛度變化體現為允許支座位移的大小與結構受力性能及穩定承載力之間的關系。Many stations of tamshui line are pieces of fine art. modern materials are used all over at elevated stations to express the spirit of chinese traditional architecture. for instance, carved picket windows made by stainless steel and wood crossbeam brackets made by steel show the unique among roofs, which were decorated with suspended mountains or rolled up
捷運淡水線很多車站本身即是藝術品，高架段的車站多以現代材料反應中國傳統建築的意象，例如：以不銹鋼做出格柵花窗的感覺以鋼材做出斗拱的意象，再配上或懸山或卷棚的屋頂造型，以同中求異。Tunnel vault and the surface of the side wall, play a firing prevention and heat insulation protecting roles, prevent the armored concrete reducing its intensity when the temperature rapidly heating up because of fire, avoid the tunnel from exploding and protect effectively the lining reinforcing steel bar not to lose supporting capacity so as to avoid the tunnel collapsing
隧道防火塗料塗噴在隧道內的拱頂和側壁的表面，起防火隔熱保護作用，防止隧道內鋼筋混凝土在火災中迅速升溫而降低強度，避免混凝土炸裂、有效保護襯內鋼筋不會失去支撐能力而避免隧道垮塌。The model scale is 1 / 5. the distribution of the stress at the top section of arch ribs in different load cases is obtained by simulating the construction procedure
