摘要
目前,建筑水平的提高以及基坑施工期间事故频发等因素,对基坑进行变形监测以及监测精度也越来越重要。基坑水平位移监测有小角度法和极坐标法等多种方法,随着全站仪仪器开发生产的先进性,其仪器中的点投影测量方法在基坑水平位移监测应用中表现出更加方便、快捷、直观的优点,在节省外业观测时间和提高内业处理效率的同时,也更加精确地反映了基坑的变化,从而能够更快、更准确地对基坑变形进行预测分析。
At present,the improvement of the construction level and the frequent accidents during the construction of the foundation pit make it more and more important to monitor the deformation and monitor the accuracy of the foundation pit.Horizontal displacement monitoring of foundation with small angle and polar coordinate method and other methods,with the advanced development and production of the total station instrument,point projection measuring method of the instrument to show the advantages of more convenient and intuitive application in monitoring horizontal displacement of foundation pit,in the day outside the observation time and improve industry efficiency in industry at the same time,more accurately reflect the changes to pit,faster,forecast and analysis of foundation pit deformation more accurately.
