在加勁設計工程實務裡，設計單位採用之套裝軟體設計理論因人而異，成果更是五花八門，業主亦無暇深入了解，尚且國內無標準規範，導致可能經費浪費，標準不一，實造成工程驗收上之困擾。 本研究乃針對 版6M以下之加勁式擋土牆，以地工格網為例，發展出一套符合設計準則要求之非線性最佳化數學模式，以供業界作為評核其它設計方法之用；考量靜態、動態、動靜態之最佳化設計模式裡，比較出敏感度分析之差異性，可視出決定目標值之真正變數與參數。與同理論設計方法比較出實有較好之績效，成果優。 在考慮設計之基本假設條件下，符合FHWA規範下，同時依工地實際現況作靜、動態之變數及參數調整，可於最短之時間內，迅速有效求得最佳解。在敏感度分析上更可直接果決地作思考空間探討，作適度調整以因應工程環境之不同需求。 In the design project of reinforce, design units uses packaged software of their own choice, causing too many brands for companies to give in-depth understanding. On the other hand, there are no criteria in the country to give appropriate guidance, so it may end up spending unnecessary money in varied standards and causing troubles in project inspection and engineering acceptance. The research focuses on reinforced soil retaining wall under 6M in version. Take ground grid as an example, a set of non-lineal optimum mathematic mode meeting the design requirement has been developed for the industry assessing other design methods. In consideration of optimum design modes in static state, dynamic state, and static & dynamic state, differences of sensitivity analysis have been compared, in which the actual variables and parameters of target value can been determined. Compared with similar theory design methods, this method has shown better performance and excellent result. Making Consideration under basic hypothesis of design, and in accordance with FHWA criteria, variables of statistic, dynamic state and parameters have been adjusted. The optimum solution can be sought in a short time. In the sensitivity analysis, a direct and decisive thinking can be obtained and make proper adjustments to meet various demands of project environments.
