hollow pier
解釋
空心墩-
So the deterministic analysis method for seismic response of thin - wall hollow pier is discussed in this paper, find the character of the structure ' s linear and nonlinear response when earthquake takes place, the purpose is to provide a reference to engineer design dept to finish their special program of analyzing pier ' s seismic response, some advice have been given for pier ' s design
有鑒於此，本文對薄壁空心墩地震反應的確定性分析方法進行了一些探討，研究了薄壁空心高墩在地震作用下線性和非線性反應的一些特性，其目的是為工程設計部門應用時程分析法編制專用的環形薄壁空心墩抗震分析軟體提供一個參考，同時對薄壁空心墩的抗震設計提出一些建議。 -
The study result indicated that the free vibration of the dam will be affect by opened hollow and pier added on dam
研究表明考慮孔口和閘墩對大壩的自振特性有一定的影響。 -
The study result that there is slightly stress concentrated in the aera of the dam which with opened hollow and pier added. by the tension stress is more over the design intension, we need more reinforcement to resisted the stress
結果表明在孔口和閘墩附近出現了程度不太嚴重的應力集中現象，但拉應力超出抗拉設計強度較多，有必要採取配筋等措施來抵抗動力作用下的拉應力。 -
The main component of this article is study arch - dams stress distribution in difference earthquake and difference water level with finite element analysis. and the study compare the adversed stress distribution on the position whether existed opening hollow areas and pier or not
在考慮了壩身開孔和閘墩的存在後，壩體應力場也將發生一定的變化，特別是在開孔及閘墩附近，與不開孔及無閘墩情況相比將會有顯著的不同。 -
For vibration mode - shape, this affect is more severity on high rank stage vibration than low. with opened hollow and pier added on dam, the frequency of vibration decline. although the array of low rank vibration mode - shape is changed, the dynamic characteristic of the dam not in evidence change
對于振型而言，這種影響對低階振型比高階振型大，考慮孔口和閘墩后，大壩的自振頻率有所降低；在低階振型中有一部分的排列順序（大小關系）發生了變化，但這些變化不致使大壩的動力特性發生顯著的改變。 -
The result of the study included two aspect : one is the affection when hollow opened and pier on arch - dam with statics calculation, earthquake response spectrum analysis and analysis of time - history i. e step - by - step integration analysis
本文完成的主要工作有兩個方面：一是通過靜力分析、反應譜分析和時程分析研究壩身開孔及閘墩對壩體整體動力反應的影響。 -
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。
