大跨PC连续梁桥施工监控评价研究

Research on Construction Supervision Evaluation of the Long-span Pre-stressed Concrete Continuous Beam Bridge

基于桥梁施工监控具体内容建立大跨PC连续梁桥监控评价体系,根据关联分析法找出误差较大的施工阶段进行原因分析并对桥梁施工监控各评价指标评分和分级,采用不确定型层次分析法计算评价指标权重向量,运用模糊综合评价对大跨PC连续梁桥施工监控效果进行综合评价.根据该评价原理,应用科学计算软件MATLAB编程将评价方法程序化.通过应用该程序对210分离式立交桥监控效果评价,验证了该方法用于大跨PC连续梁桥监控评价的可行性.

The construction supervision evaluation system of long-span pre-stressed concrete continuous beam bridge is established on the basis of the concrete contents of bridge construction supervision. The relational analysis, by which the construction stage with lager error is searched to find out the reason, is used to score and grade the supervision evaluation index. The evaluation index weight vec- tor is obtained through uncertain analytic hierarchy process. Then the construction supervision effect of long-span pre-stressed concrete continuous beam bridge is evaluated by fuzzy comprehensive evalua- tion method. Based on this evaluation principle, the program of this method is developed based on sci- entific calculation software MATLAB. Using the program to evaluate the supervision effect of 210 separation type overpass, the feasibility of this method in supervision evaluation system of long-span pre-stressed concrete continuous beam bridge is verified, and the evaluation program is also useful in supervision evaluation.
