【摘要】：我国是以煤炭开采为主的资源型国家,人们对煤炭的需求量日益增大,“三下”开采的危害日益明显。由于地下大面积采空区的出现,导致上覆岩体在自重的影响下产生变形与破坏,直接作用到地表使其发生移动与变形,进而造成采空区上方建筑物受到不同程度损害,所以如何做出准确的、科学的评价具有重大意义。考虑建筑物损害评价影响因素比较多,如何合理的建立一个建筑物损害评价模型去判断建筑物损害情况,成为专家学者们研究的一大热点问题。针对传统方法选择影响因素的不足之处,结合力学和开采沉陷学等理论从开采方法和地质条件、建筑物自身特征、建筑物基础下土壤特征、其它影响因素这四个方面的29个因素进行分析。采用AHP和模糊综合评价法建立采煤沉陷区建筑物损害评价模型,将传统定性描述和半定量分析的评价方法转变成定性与定量分析相结合的方法,使整个评价转化为定量化计算的过程。重点分析指标体系的建立、指标因子权重的计算方法和隶属函数的构建等问题。应用此模型对铁法晓南矿区的张庄村委会建筑物的进行评价,得出其损害等级,并与传统评价方法得到的结果相似,具有一定的准确性和实用性。
[Abstract]:China is a resource-based country with coal mining in the main. The demand for coal is increasing day by day, and the harm of "three down" mining is becoming more and more obvious. Because of the emergence of large underground goaf, the overlying rock mass is deformed and destroyed under the influence of deadweight, which directly affects the surface of the earth to make it move and deform, and then causes the buildings above the goaf to be damaged to varying degrees. So how to make accurate, scientific evaluation has great significance. Considering the influence factors of building damage evaluation, how to reasonably establish a building damage evaluation model to judge the damage of buildings has become a hot issue of experts and scholars. In view of the shortcomings of traditional methods in selecting the influencing factors, combined with the theories of mechanics and mining subsidence, the characteristics of mining methods and geological conditions, the characteristics of buildings themselves, and the soil characteristics under the foundation of buildings are discussed. Other factors affecting these four factors of 29 factors were analyzed. AHP and fuzzy comprehensive evaluation method are used to establish the damage evaluation model of buildings in coal mining subsidence area. The traditional qualitative description and semi-quantitative analysis evaluation method are transformed into the combination of qualitative and quantitative analysis. The process of transforming the whole evaluation into quantitative calculation. The establishment of index system, the calculation method of index factor weight and the construction of membership function are analyzed. The model is used to evaluate the buildings of Zhangzhuang Village Committee in Tiefa Xiaonan Mining area, and the damage grade is obtained. The results are similar to those obtained by traditional evaluation methods and have certain accuracy and practicability.
