【摘要】：西部地区的城市化进程加快使其当地社会经济得到了快速发展,但由于过快的城市化进程使生态环境遭到了不同程度破坏,使城市建设与生态环保形成了矛盾关系,造成地质灾害频繁发生。因此提出对西部代表城市山城重庆的建筑进行抗泥石流设计与规划,将地质灾害给建筑带来的危害程度降到最低。首先,在抗灾建筑设计中应用到异形柱-密肋复合墙体结构,通过建立有限元模型先对密肋复合结构墙进行力学性能及受力形态变化特征分析,基于复合材料学理论,将异形柱与复合墙体结合通过简化方式获取复合墙体简化模型,实现对模型结构的力学分析及弹塑性分析;其次,利用模糊数学理论建立异形柱——密肋复合墙结构建筑评价体系,通过单项测评、权重求解及综合测评对该建筑结构进行损坏程度等级划分。利用泥石流荷载仿真实验对异形柱——密肋复合墙结构建筑进行实验研究,结果表明文中设计的抗泥石流建筑符合抗灾标准,有效地减少了泥石流带来的危害。
[Abstract]:The accelerated process of urbanization in the western region has made the local social economy develop rapidly, but the ecological environment has been destroyed to varying degrees due to the rapid urbanization process, which makes the contradiction between urban construction and ecological environmental protection formed.Geological hazards occur frequently.Therefore, the paper puts forward the design and planning of anti-debris flow for the buildings in Chongqing, which is the representative city of mountain city in the west of China, so as to minimize the harm caused by geological disasters to buildings.Firstly, the special shaped column-ribbed composite wall structure is applied in the design of disaster-resistant buildings, and the mechanical properties and mechanical characteristics of the multi-ribbed composite wall are analyzed by establishing the finite element model, which is based on the theory of composite materials.The simplified model of composite wall is obtained by combining the special-shaped column and composite wall, and the mechanical analysis and elastic-plastic analysis of the model structure are realized. Secondly,The evaluation system of special-shaped column-ribbed composite wall structure is established by using fuzzy mathematics theory. The damage degree of the structure is classified by single evaluation, weight solution and comprehensive evaluation.An experimental study on special-shaped column-ribbed composite wall building is carried out by using debris flow load simulation experiment. The results show that the anti-debris flow building designed in this paper conforms to the anti-disaster standard and effectively reduces the hazard caused by debris flow.
