梁振江 的英文怎麼說
中文拼音 [liángzhènjiāng]
梁振江
英文
liang chon kong-
Strip - shape underground structures such as the tunnels and tubes for various uses can be treated as a beam on elastic foundation under earthquake condition ， although there exists soil - structure interaction ， the foundation soil vibration is dominant in other words ， analysis of earthquake response of the soil is essential to this end ， simplified models ， ( i. e equivalent mass system models based on some equivalence criteria ) are proposed ， instead of a general 3 - d continuum model in this study ， equivalence criteria are proposed and the simplified models are compared the single - mass - string model is proved to be valid and therefore applied to the analysis of earthquake response of the pearl river immersed tunnel
條裝地下結構如隧道、各種埋設管道等一般可看作彈性地基梁進行靜力及動力分析在地震條件下，結構與土相互作用，但土的振動成為主要因素為分析土的地震響應需把基土這一三維連續體作簡化處理，簡化成為等效多質點模型本文著重探討這種簡化模型的建立方法，推導等效方程，通過幾種簡化體系的分析比較，論證單質點串體系的合理性，並將其應用到廣州黃沙芳村珠江水下隧道工程的地震響應分析，為抗震設計提供依據The thesis is aimed at presenting a procedure to establish a baseline finite element model of the qingzhou cable - stayed bridge over the ming river, fuzhou, china that was newly constructed. its main span length of 605m is the longest in the world among the completed composite - deck cable - stayed bridge. the proposed procedure includes several tasks : initial finite element modeling base on the design drawings, field loading tests and ambient vibration tests, and finite element model calibration with the test results
本文以主跨605m的結合梁斜拉橋? ?青洲閩江大橋為背景，首先根據設計圖紙建立該橋完整的初始空間有限元模型，然後根據通車前現場靜力試驗和環境振動試驗結果對初始有限元模型進行校正，通過參數的調整使模型靜、動力計算結果與實測值吻合。Wan zhou yangtze river bridge is the establishing large span steel truss bridge now, and the property of it is the lower stiffness of the main girder. when the speed is high, the analyses and the vibration control of vehicles and bridge are very important, especially the dynamic lateral response of the system
萬州長江大橋是目前在建的大跨度鋼桁架拱橋，其特點是主梁結構剛度較小，在高速行車速度下，對起車橋耦合振動分析及其控制尤其是車橋系統橫向動力響應研究則尤為重要。This paper combine the properties of railway bridge to establish the model of vehicle and three - dimension finite model of wan zhou yangtze river bridge individually, then according to the basic hypothesis and through the relations of geometry displacement compatibility and force and adopting the mode superposition to establish the coupling model of vehicles and bridge
本文結合鐵路橋梁的特點，分別建立了車輛模型和萬州長江大橋的三維有限元模型，根據橋梁結構的基本假設，採用模態綜合法，通過輪對與輪軌之間的幾何相容關系和力的關系建立了車橋耦合振動模型。Finally, nanjing yangtze river bridge on peking - shanghai high speed railway which is a three - pylon cable - stayed bridge is analyzed. in buffeting analysis, analysis result in time domain is compared with that in frequency domain. the effects of pylon wind speed field and nonlinear factors are taken into account
最後，以京滬高速鐵路南京長江大橋為工程背景，比較了橋梁時域抖振分析和頻域抖振分析的一致性，分析了橋塔風效應和非線性因素對結構抖振響應的影響。分享友人
