【摘要】：我國是以煤炭開采為主的資源型國家,人們對煤炭的需求量日益增大,“三下”開采的危害日益明顯。由于地下大面積采空區(qū)的出現(xiàn),導(dǎo)致上覆巖體在自重的影響下產(chǎn)生變形與破壞,直接作用到地表使其發(fā)生移動與變形,進(jìn)而造成采空區(qū)上方建筑物受到不同程度損害,所以如何做出準(zhǔn)確的、科學(xué)的評價具有重大意義�？紤]建筑物損害評價影響因素比較多,如何合理的建立一個建筑物損害評價模型去判斷建筑物損害情況,成為專家學(xué)者們研究的一大熱點(diǎn)問題。針對傳統(tǒng)方法選擇影響因素的不足之處,結(jié)合力學(xué)和開采沉陷學(xué)等理論從開采方法和地質(zhì)條件、建筑物自身特征、建筑物基礎(chǔ)下土壤特征、其它影響因素這四個方面的29個因素進(jìn)行分析。采用AHP和模糊綜合評價法建立采煤沉陷區(qū)建筑物損害評價模型,將傳統(tǒng)定性描述和半定量分析的評價方法轉(zhuǎn)變成定性與定量分析相結(jié)合的方法,使整個評價轉(zhuǎn)化為定量化計算的過程。重點(diǎn)分析指標(biāo)體系的建立、指標(biāo)因子權(quán)重的計算方法和隸屬函數(shù)的構(gòu)建等問題。應(yīng)用此模型對鐵法曉南礦區(qū)的張莊村委會建筑物的進(jìn)行評價,得出其損害等級,并與傳統(tǒng)評價方法得到的結(jié)果相似,具有一定的準(zhǔn)確性和實(shí)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.
