RESEARCH ON SUPPLEMENTARY MONITORING METHOD OF REINFORCED CONCRETE SUPPORTING AXIAL FORCE
Due to the influence of concrete shrinkage and creep,temperature and other factors,the axial force calcu-lated by the conventional monitoring method is different from the actual axial force.In order to verify the monitoring results of the conventional method and add an additional axial force measurement method,this paper proposes that the coordinates of both ends of the support can be measured at the same time before the excavation of the foundation pit,and if the measured values of the support axial force are abnormal,the support axial force can be calculated by continuously monitoring the deformation of both ends of the support.The results show that the variation trend of axial force supplementary monitoring method is close to that of conventional monitoring method,the monitoring data is rel-atively stable,and the overall calculation result of axial force supplementary monitoring method is small.Therefore,the method can be used as an effective supplement to conventional monitoring methods.
