In the construction of bridges, construction management is very important. Reliability or safety is dependent on the accuracy of construction even though design is done precisely. In this syudy, an attempt is made to introduce the fuzzy set theory into the finite element analysis in order to improve the accuracy of the analysis. It is also attempted to develop a practical method for system identification of errors involved during construction and optimal adjustment of cable tension forces and cambers.The formulation of the fuzzy finite element analysis was done and its efficiency was validated through a simple numerical example of simply supported plate. For the construction management of bridges, a new practical method was developed based upon fuzzy regression analysis and fuzzy mathematical programming. Comparing the usual adjusting methods based on nonlinear optimization technique, this method can improve the convergency reaching the optimal solution and reduce the computation load and time.

在桥梁施工中，施工管理是非常重要的。可靠性或安全性取决于施工的准确性，即使设计是精确的。本文尝试将模糊集理论引入有限元分析中，以提高有限元分析的精度。建立了模糊有限元分析的数学模型，并通过简支板算例验证了模糊有限元分析方法的有效性。针对桥梁施工管理问题，提出了一种基于模糊回归分析和模糊数学规划的实用方法。与常用的基于非线性优化技术的调整方法相比，该方法提高了收敛速度，减少了计算量和时间。
