| Abstract: | Based on the approximate analytic formulas, an evaluation system for the static behavior of self anchored double tower cable stayed bridge was established. Mechanical evaluation indexes and corresponding parameters were summarized. The sensitivity of various factors was analyzed for the structural mechanics indexes. Then, the effects of mechanic properties of structure system were studied in detail for the mechanical parameters. The research achievement can provide a reference for the conceptual design of self anchored double tower cable stayed bridge. |
