| 摘 要： | 为了研究采动区建筑物附加地基反力的变化规律，采用采动区建筑物地基、基础和结构协同作用力学模型，研究了建筑物位于采动区不同位置时附加地基反力的分布变化规律，指出地表曲率变形值是控制附加地基反力大小及分布形态的主导因素；并研究了建筑物长度、弹性模量、地基系数、开采厚度、建筑物高度等各种因素对建筑物附加地基反力的影响规律，同时建立了附加地基反力最大值与各影响因素之间的关系式.

| Abstract: | In order to study the change laws of additional ground reaction force of buildings in mining area,by adopting coordinating action mechanic model of ground,foundation and structure of buildings in mining area,studied the distribution and change laws of additional ground reaction force of buildings in mining area,and pointed out that the ground curvature is the dominant factor to control the value and distribution shape of additional ground reaction force.It also studied effecting laws on building additional ground reaction force caused by different factors such as building length,elastic modulus,ground coefficient,mining thickness and building height,and established the relationship formula between maximum additional ground reaction force and respective influencing factors. |
