| Abstract: | In design of horizontal deformation monitoring network of long bridge, which is about 2900m and has 72pillars, this paper proposes to separate the whole baseline into several parts. The straight line triangulateration net which has high accuracy and reliability can be used as the first order control net. Based on the computer aided optimization technique, the best division number of baseline and the optimal design of triangulation net are resolved under consideration of accuracy, reliability and cost. |
