Discussion on the truncated cone banking construction lofting and quantity calculation;

It is important that useing the total station instrument to intravers servey, topographic servey, construction lofting and so on.

Laying off curve is the primary content of the technique design and construction setting-out in the linear engineering,for instance highway、railway、pieline and so on,and it is the primary competent of engineering surveyor in everyday work.

Taking the control network of Zhanghewan Pumped Storage Power Station for example,the comparative calculation is made;and the construction setting-out and measurement method for the complex form and structure with multi.

After the application of GPS static survey and total-station instrument in the construction setting-out of bridge in Hangzhou gulf,it can be concluded that this method can guarantee the speech and accur.

The paper presents the contents,methods and feature of the construction setting out for highrise span road in city.

Then proceed to discuss a new method of gradual bending sector construction setting out through electronic total station directed prism moving.

The papor first introduces the key application of General Total Station,then emphatically expounds the method and formula of coordinate calculation of road central line,grade separation turn-to-turn central line,abutment central point and axial point of reference Thus the concrete operation of General Total Staion in highway construction layout is clarifie

This article unifies the examples to introduce the application of AutoCAD technology for the material computation and the setting-out survey in the project survey.
