钢管混凝土拱桥力学性能研究(含MIDAS)

钢管混凝土拱桥力学性能研究(含MIDAS)(开题报告,外文翻译,论文说明书13000字)
摘要
自从20世纪90年代，随着我国社会经济的发展，人民对我国交通基础设施建设的要求也逐渐提高，因此我国桥梁建设事业也得到了迅猛发展。尤其从21世纪开始，得益于各种施工方法和理论技术的成熟与改进，我们建设了多种多样的大跨径桥梁。为适应现代交通以及环境保护的需求，我们需要施工速度快、强度高、质量轻、造型优美的新型材料新结构，钢管混凝土拱桥正好满足上述要求。
研究钢管混凝土拱桥的相关力学性能的目的即为深刻地理解这种新型材料新结构，方便将其运用到实际中去，对于满足交通事业建设需求和为国民经济发展、人民生活水平提高有重大意义。
本文研究重点为施加不同荷载对王安石大桥的受力性能的不同影响。
拟采用的技术方案及措施：结合王安石大桥设计图纸建立MIDAS空间模型，在其他条件相同的情况下，通过施加不同荷载探究其对王安石大桥的受力性能的不同影响。

ABSTRAC
With the development of our country’s social economy, the people’s demand for China’s transportation infrastructure is gradually increasing since the 1990’s. Therefore, the bridge construction in China also has developed rapidly. Especially since the 21st century, benefit from the maturity and improvement of various construction methods and theories and technologies, we have built a variety of long-span Bridges. In order to adapt to the needs of modern transportation and environmental protection, we need a construction speed、high strength、light weight、beautiful new structure. Concrete-filled steel tubular arch bridge just meets the above requirements.

  The purpose of studying the mechanical properties of concrete-filled steel tubular arch bridge is a deep understanding of this new material and new structure and easy to put it into practice. It is of great significance to meet the needs of traffic construction, national economic development and the improvement of people’s living standards.
.
Technical scheme and measures to be adopted: MIDAS spatial model is established based on the design drawings of Wangshi Bridge. Under the same other conditions, different loads are applied to explore the different effects on the mechanical properties of Wangshi Bridge.
