| Abstract: | The accuracy formulas of three-point coordinates to calculate the centre of a circle coordinate are deduced. Efforts are also made to analysis the effects of three point configuration on accuracy of the centre of a circle. It is proved in this paper that equilateral triangle arrangement is the best configura- tion. The adjustment method of the centre of a circle coordinate by using four-point or more points is discussed. Then a steel casing simulative test is carried out, and the test data are calculated and analysed. The analysis results find a better application in the steel casing center position checking in Sutong Bridge. |
