x-bridge

基本解释

Based on the coupled vibration theory, dynamical models and equations of motion were set up respectively to an X-style arch bridge and vehicles.
采用车桥耦合振动理论，分别建立了铁路车辆和提篮拱桥的动力模型及其运动方程。
Compare with the traditional concrete-filled tube arch bridge, the X-shaped arch bridge has the predominance on the stability in cross, the span and the bearing capacity and so on.
相对于传统钢管混凝土拱桥而言，提篮拱桥在纵、横向稳定性、桥梁跨度和承载能力等方面具有独到的优势。
Furthermore, from the stability analysis of the X-type double ribs arch bridge, this paper show how changes inclined inward angle would affect the stability, and the optimum design is presented.
其次，从变宽度X型肋拱桥稳定性分析出发，给出内倾角度对稳定的影响并特别提出了最优角度。
