新建工程基礎開挖階段設計之安全性,在設計階段要針對不同個案實際去考量安全性時,就有安全及成本2個規畫目標產生輕重取捨的衝突存在,以安全為重,成本就增加,以成本為重,又有安全上的疑慮,取得最適規劃模式,是本研究的重點。
本研究除了考量安全性及經濟性外,並加入設計者主觀規劃偏好因素,希望更客觀來分析基礎開挖階段之安全支撐的規劃設計,故本研究結合模糊理論、無異曲線、效率前緣及資料包絡分析法等研究方法做論述,比較不同之投資組合,得到一條報酬最高之投資組合效率前緣曲線,以無異曲線代表設計者的規劃偏好,以模糊理論,選擇設計者偏好。
無異曲線斜率代表設計者規劃建築工程基礎開挖時的規劃偏好,當無異曲線與效率前緣曲線相切,該切點即為規劃偏好一併列入考量之建築工程基礎開挖安全支撐之最適規劃模式,此模式另以安全支撐比例設計參數,作為不同組合之設計參數,非位於效率前緣之建築工程基礎開挖,發展一規劃效率評估之方法論,以效率前緣上之表現較佳之規劃作為標竿學習的對象。
The safety of the design of the foundation excavation stage of the new project. When the safety is considered in the design stage for different cases, there are conflicts between the safety and cost of the two planning targets. The safety is the priority and the cost is increased. Taking cost as the priority and safety concerns, and obtaining the optimal planning model is the focus of this study.
In addition to considering safety and economy, this study adds the designer's subjective planning preference factors, and hopes to analyze the planning of safety support in the foundation excavation stage more objectively. Therefore, this study combines fuzzy theory, indifference curve and efficiency front. And the data envelopment analysis method and other research methods are discussed, and the different investment portfolios are compared to obtain the highest-paying portfolio efficiency leading edge curve. The indistinct curve represents the designer's planning preference, and the fuzzy theory is used to select the designer's preference.
The slope of the indifference curve represents the planning preference of the designer when planning the foundation excavation of the building engineering. When the indifference curve is tangent to the efficiency leading edge curve, the cutting point is the construction engineering foundation excavation safety support that is included in the planning preference. The optimal planning mode, which uses the safety support ratio design parameters as the design parameters of different combinations, is not based on the efficiency of the leading edge of the building engineering excavation, develops a methodology for planning efficiency evaluation, and performs better on the efficiency front. Planning is the object of learning as a standard.
