hollow pier meaning in English
空心墩
空心桥墩
Examples
- 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
而随着铁路建设事业的发展，山区铁路要求修建更多的高桥，因此桥墩越来越高，桥墩也由实心变为空心，目前对于薄壁空心墩振动特性尤其是非线性特性的研究较少，桥梁抗震设计规范中也少有涉及，研究薄壁空心墩的地震反应，对完善我国桥梁设计规范具有重要的意义。 - 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
本文完成了以下几项工作： ( 1 )分析了桥墩抗震计算的地震力理论和桥墩结构抗震动力学方法； ( 2 )研究了将桥墩简化为平面杆系结构时结构在地震作用下的计算模型和计算方法； ( 3 )编制了薄壁空心墩地震反应分析程序，可以对桥墩线性和非线性反应作出分析，并验证其正确性； ( 4 )通过改变设计参数进行对比计算，提出了一些在桥墩抗震设计中应该注意的问题以及相应的解决方法。 - 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
有鉴于此，本文对薄壁空心墩地震反应的确定性分析方法进行了一些探讨，研究了薄壁空心高墩在地震作用下线性和非线性反应的一些特性，其目的是为工程设计部门应用时程分析法编制专用的环形薄壁空心墩抗震分析软件提供一个参考，同时对薄壁空心墩的抗震设计提出一些建议。
