摘要
该文运用角差图解法与测量误差理论及高等数学极值原理 ,论证了前方交会法观测烟囱变形的测定精度由变形强度系数决定 ,找到了该法的最佳设计方案 ,并通过烟囱变形观测实践 ,验证了该文提出的优化设计理论的正确性。
The paper used angle difference diagram, survey error theory and mathematics limit principle to discuss the measurement accuracy of chimney inclination observed by forward crossing method that is determined by coefficient of deformation strenth of the chimney. The optimum design of the method is found out. Through observation of chimney inclination, the correctness of optimized design suggested in the paper is demonstrated.
