elevation element 中文意思是什麼
elevation element
解釋
測高元件-
And in combination with cable replacement engineering of sichuan qianwei bridge, based on the bridge elevation and cable forces measured before cable replacement started, using finite element software bsas developed by southwest jiaotong university build analysis modeling, by means of cable forces adjustment and so on to make the cable forces of modeling approach the cable forces measured before cable replacement started, according to the scheme of primary design, aimed at cable replacement process, simulation analysis is done and get the calculated results
然後以四川犍為岷江大橋換索工程為背景，以換索前實測的索力和線形為換索設計基準，應用西南交通大學開發的橋梁結構分析軟體bsas建立換索分析模型，通過調索等技術手段使模型索力與換索前實測索力逼近，以此為換索的出發點，按原換索設計的方案與工序，對換索進行全過程分析，得到換索完工後的計算索力和線形。 -
To avoid the probability, engineer calculate the cable tension and the pre - rising elevation with finite element theory, it cost much time in design the program and repeat calculation, the other hard work is to find out the place where the cables located in span arch structure, its must find out the optimized result manually which restrict the design work. recent years, lots of commercial fea software develop rapidly. engineers focus on the solution of commonness problems by the software existed
為了解決這個問題，設計人員常常採用有限元方法計算扣索受力及拱肋控制標高，並根據計算結果設計扣索吊裝位置，在此過程中大量重復編程及計算工作佔用了很多工作時間，另外在扣索吊裝位置的選定過程中又沒有明確的方法，只能根據大量的計算結果人工尋找優化方案，這些都制約著設計工作的開展。 -
During the course of stress calculation, the concrete watertight wall and the soil around are supposed to be linear elastic material, the onsolidation of dam is supposed to be completed before the watertight wall is constructed, the contact element is adopted to simulate the interface between the dam and watertight wall, and the completed before the watertight wall is constructed, the contact element is adopted to simulate the interface between the dam and watertight wall, and the influence towards the stress of watertight wall when water elevation changes is calculated by fem
應力計算時將砼防滲墻及周圍土體假設成線彈性材料，假設在防滲墻施工時壩體固結已經完成，用接觸單元模擬壩體和防滲墻之間的接觸面，利用有限元計算出水位變化對防滲墻應力的影響。 -
