| Abstract: | It is proposed that the coordinate method should be used as the solution to the problems caused by narrower construction sites where the traditional methods are not applicable.An analysis is carried out on the accuracy of horizontal displacement monitoring by Total Station coordinate method.By engineering practice and results analysis,it verified the requirements for different levels of horizontal displacement of foundation pit.Only if the appropriate operating Total Station was selected,the method can meet the requirements to ensure accuracy and improve operational efficiency. |
