Through the example of construction project,this paper gives an introduction to the principle?method and practice in the measurement of circular arc detail.

Through contrastive experimentation, a reasonable mix proportion for a kind of high-intensity and high-performance concrete is determined, and this proportion is fit for thin arc-shaped steel tube.

A new method for constructing circular arc;

Representing rational cubic circular arc by normalized totally positive or generalized Ball methods

If the section is a circular arc in the spatial slanting plane,the circular arc is the extremely reasonable bore hole path curve for slide drilling in minimum curvature method.
