空心橋墩 的英文怎麼說
中文拼音 [kōngxīnqiáodūn]
空心橋墩
英文
hollow pier-
With the development of railway construction. it needs more and more high bridges in mountain areas, so the pier becomes higher than before. and it becomes from solid to hollow. presently, it has little research on the thin - wall hollow pier ' s vibrational characteristic especially on non - liner characteristic, and it has scarcely referred in the bridge ' s criterion about earthquake resistance, so it has great sense on fulfillment of the our bridge ' s criterion to research the thin - wall hollow pier ' s seismic response
而隨著鐵路建設事業的發展，山區鐵路要求修建更多的高橋，因此橋墩越來越高，橋墩也由實心變為空心，目前對于薄壁空心墩振動特性尤其是非線性特性的研究較少，橋梁抗震設計規范中也少有涉及，研究薄壁空心墩的地震反應，對完善我國橋梁設計規范具有重要的意義。The following task has been finished : ( 1 ) analysis the pier ' s seismic force theory and dynamics method. ( 2 ) resarch the computational model and method of the thin - wall hollow pier when it is predigested plane bar structure ; ( 3 ) the paper complete the program to compute the pier ' s seismic response, which can analyze pier ' s linear and nonlinear response, also its correctness has been validated. ( 4 ) use the program to compute some samples, some problems and their relevant resolvent have been offered
本文完成了以下幾項工作： （ 1 ）分析了橋墩抗震計算的地震力理論和橋墩結構抗震動力學方法； （ 2 ）研究了將橋墩簡化為平面桿系結構時結構在地震作用下的計算模型和計算方法； （ 3 ）編制了薄壁空心墩地震反應分析程序，可以對橋墩線性和非線性反應作出分析，並驗證其正確性； （ 4 ）通過改變設計參數進行對比計算，提出了一些在橋墩抗震設計中應該注意的問題以及相應的解決方法。
