摘要
受采动影响建筑物的移动变形和附加应力分布规律十分复杂,与建筑物的长度、高度、建筑材料、结构、刚度、地基性质、地下开采情况、建筑物所处的位置等多种因素有关.本文综合采用矿山开采沉陷学、矿山岩体力学、数理科学等多学科的知识,建立了采动区建筑物地基、基础与结构协同作用力学模型.该模型可以计算采动区建筑物移动变形和各种附加内力,并采用可视化VB语言编制了相应的计算程序,通过计算示例进行了验证,为今后采动区建筑物的保护和设计提供了理论基础和计算工具.
The law of movement and deformation and additional stress distribution of building in mining area is very complex because it has relationship with many factors such as the length, height, material, structure, stiffness, foundation coefficient and location of buildings. Using mining subsidence, rock mass mechanics and advanced mathematics coordinating work model of ground, foundation and structure of building in mining area was established. This model can be used to calculate the movement and deformation and additional stress of buildings in mined area. By means of Visual Basic the corresponding calculation programs were developed. The programs were verified by practical examples. This work can provide theory foundation and calculation method for protecting and designing of buildings in mined area.
