Analysis of the effect that the construction measure generates to the masonry structure's anti-deformation of the goaf

The biggish surface deformation of subsidence area of coal mining (inclination,horizontal deformation and curvature) will destroy the existing masonry buildings,such as inclination,crack and collapse,etc.On the basis of summarizing the current situation of coal under the "three",estimate all kinds of surface deformation value according to the concrete geologic conditions and mining conditions of the proposed mine lot.Establish typical multistory masonry structure by using the ideology of finite element whole model.Calculate the force conditions of the masonry structure's wall in the situation of surficial whole inclination,horizontal and tensile deformation,differential settlement caused by mining subsidence in the proposed mine lot.Compare to the force conditions of the wall in normal work condition.Make quantitative analysis on the influence to wall stress under various deformation conditions which caused by setting ring beam and constructional column or not and transformation of sectional dimension.Summarize the influence law on masonry structure under surface deformation caused by construction measure in accordance with analysis results.
