文章介绍了城市深基坑监测的目的、意义、方法及测量的精度估算等。指出了以前部分监测方法的不足,提出了利用全站仪对基坑进行的3维变形观测的方法,以及对该测量方法的精度论证。得出了该方法不但能提高测量精度、效率,而且节省了资源等结论。 更多还原

【Abstract】 This article introduces the purpose,significance,methods and measurement accuracy estimate of the city deep foundation pit monitoring,and so on.It pointed out the deficiency of the monitoring method of the previous department,and proposed using Electronic Total Station to make 3D deformation observation of foundation pit.The accuracy argumentation of the measurement method is obtained.The method not only improves the accuracy of measurement,efficiency,and saves resources. 更多还原
