采动区建筑物地基反力分布规律

基于相似模拟试验、现场实测、数值模拟及理论分析，系统研究了采动区建筑物地基反力分布规律，获得了地基反力与建筑物所处的位置、刚度、长度、地基系数、开采厚度的关系：1)位于最大曲率点附近时，地基反力最大，位于最大下沉和倾斜点附近时，地基反力较小；2)地基越软弱、建筑物长度越短，地基反力越小；3)采动区建筑物地基反力大小是有限的，这些认识和结论为采动区建筑物保护和设计提供了理论基础。

Reacting Force Distribution Law of Building Foundation in Mining Area

Based on similarity simulation experiment, field measurement, numerical simulation and theoretical analysis, the systematic study concerning reacting force distribution law of building foundation in mining area was conducted. The relationship between foundation reacting force and the location, stiffness, length, foundation coefficient and mining thickness has been observed as follows: 1) the foundation reacting force is maximal when the building is near the point of maximal curvature, but it is rather small when the building is near the point of maximal subsidence and maximal tilt; 2) the softer the foundation is and the shorter the building is, the smaller the reacting force of foundation will be; and 3) the reacting force of building foundation in mining area is finite. All these observations and conclusions provide a theoretical foundation for building protection and design in mining area.
