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。
However, due to the rapid urbanization process, the ecological environment has been damaged to varying degrees, so that urban construction and ecological environmental protection has formed a contradictory relationship, resulting in frequent occurrence of geological disasters. However, the urbanization in the western region of China has been the rapid development of urbanization. Therefore,this paper puts forward the design and planning of the anti-debris flow in the west of Chongqing city,which is the representative city of Chongqing, and minimizes the harm caused by geological disaster to the building. Firstly, the special- shaped columns and multi- ribbed composite wall structures are applied in the anti- disaster building design. The finite element model is established to analyze the mechanical properties and the force morphological characteristics of the multi-ribbed composite walls.Based on the composite theory, And the composite wall is combined with the composite wall to obtain the simplified model of the composite wall by the simplified method. Then, the mechanical analysis and elasto-plastic analysis of the model structure are realized. Secondly, using fuzzy mathematics theory to establish the special- Evaluation, weight and comprehensive evaluation of the building structure of the damage to the level of division. The experimental results show that the anti - debris - flow structure designed in this paper is in accordance with the standard of anti - disaster, which effectively reduces the harm caused by the debris - flow.
