建筑物塌陷损坏评价的物元模型及其应用

矿产采掘和地下水资源开采造成的地表塌陷是一类较为严重的地质灾害,地表的塌陷必然会对依附于地球表层的建筑物造成不同程度的损害,建筑物损害的量化评价是地表塌陷损害工程评估的一项重要内容。本文应用可拓学的理论和方法,基于可拓学中的可拓集合变换和相关函数分析法,给出了受塌陷影响建筑物损害评价的经典域物元和节域物元,并建立了建筑物损害量化评价的物元模型。通过具体的计算示例说明了该方法的应用步骤,并对该方法的合理性进行了验证,为建筑物塌陷损坏评价提供一种新的方法。

Matter-Element Evaluation Method and Application to Damaged Buildings Caused by Ground Subsidence

The process of mineral resources mining and underground water pumping will cause ground subsidence. Ground subsidence disaster caused by mineral resources mining is the most serious kind of geologic hazard in all kinds of engineering subsidence disaster. The result of ground subsidence and deformation is that a good deal of ground surface buildings will be damaged. It is an important project to accurately e- valuate those damaged buildings for mining subsidence control and other engineering collapse repairing. This paper applies the theory and method of extenics in this research area. Based on the extensive set transform method and independent function analysis, the classical field matter-elements and segment field matter-elements have been given. A matter-element model to evaluate damaged buildings in subsidence area has been presented. This method is verified clearly through the practical example, and the use steps are demonstrated. Shown by this practical example, the model is accurate and logical in evaluating the degree of buildings' damage in ground subsidence area. It offers a new scientific method for proejccts in this area.
