| Abstract: | Based on the general formula for computing the azimuth angle of tangent line of random point in high way,this paper derives the general integral ones for computing the coordinates of middle and side stakes.According to the compound simpson formula,the general numerical models for calculat-ing coordinates of middle and side stakes are given,and the problem about determining the n,the num-ber for equal-dividing the integral interval in using compound simpson formula,is also discussed.The general models established herein lay the foun dation for the middle and side stakes layout of high way by polar method. |
