介绍了安设钢弦压力盒、钢筋拉力计对采动建筑物基础圈梁压力变化情况进行观测并分析地表下沉及地表拉伸悄况.试图采用该观测方法定量地分析地表下沉和地表拉伸对建筑物基础圈梁的影响,以便采用楔形活动基破对基础圈梁进行调整,使建筑物达到新的平衡状态,确保建筑物的稳定性.
This paper introduces the installation of steel string pressure box and steel tension meter to observe the pressure change of the foundation ring girder of mining buildings and analyze the surface subsidence and surface stretch quietly.This method is used to quantitatively analyze the surface subsidence and surface Stretching on the foundation of the building ring beam, in order to use the wedge-shaped base breaking action broken base beam to make buildings reach a new equilibrium, to ensure the stability of the building.
