A study on the theory and method of non-contact monitoring for tunnel rock deformation based on free stationing of a total station;

Application of free stationing layout method by using the linear-resection

For non contact observation system of 3 D deformation which build by WILD TC2002 total station with reflective sheet targets, the paper describes the inspecting method and inspecting result of its free stationing precision.

Application of Free Station in Digital Mapping;

Discussion on digital mapping by using the free station method

This paper introduces the measurement and adjustment method of free station, gives a very simply method of getting approximate coordinates, and discusses briefly the application of free station.

This method of measuring control point is called freely set station method.

Firstly,the method of free station overlap positioning with total station actively,theory study,error analysis and design were described,and then the results from simulation experiment and field testing were compared and confirmed.

Study on influence factors for pile stick-up stability in ocean engineering;

The segment stick-up on the seabed may suffer buckle failure under .

This paper introduces one kind of the method of digitalization mapping in sighting-difficult area: free station method,and gives account of specific method of field operation and indoor data processing.
