| 摘要(中) | 摘要 近年來政府積極地促進台灣之交通運輸便利性，目前有多項重大橋樑交通工程案正在進行，隨著施工技術的進步，多種橋樑上部的特殊結構施工法陸續被採用。暨然，橋樑工程建設需求與日俱增，且其工期長與經費龐大，遂成為交通工程之關鍵工程。對於如何規劃調度改善施工流程，已是橋樑工程重要課題之一。 台灣高速鐵路工程首次引進韓國高鐵採用的全跨預鑄吊裝工法（Full-span Pre-cast and Launching Method，簡稱FPLM）。由於，此工法在橋樑上部結構施工，作業具有高度重複循環的特性，適合以電腦模擬技術建構為電腦模擬模型進行分析。若能夠針對各資源項目、施工作業流程，進行施工作業流程之生產力分析和對資源數量進行敏感度分析，則此將有助於在施工過程之效率提昇。 本論文以全跨預鑄吊裝工法在台灣高鐵工程之C250標、C260標為案例，運用CYCLONE理論所發展的COST電腦模擬軟體為工具，對現場施工作業流程進行電腦模擬，並分析相同施工條件下，互換施工流程之模擬結果，且針對資源配置進行敏感度分析，再以專業工程師之模糊時間對於橋樑施工作業時間進行估算。研究結果發現電腦模擬技術應用於分析全跨預鑄吊裝工法是為可行的方法，若當某作業項目之施工時間數據不足以進行分析時，可依Beta分配或Triangular分配參數型態進行預測分析。以模糊時間預估作業時間也有高度準確度。此外由互換兩標之施工流程得知，影響預鑄樑施工速率主要因素在於預鑄樑生產作業施工速率。 | |||
| 摘要(英) | ABSTRACT Simulation techniques have been successfully used in the analysis and design of repetitive construction operations. An example of a highly repetitive construction process is the building of bridges using a Full-Span Pre-Cast and Launching Method (FPLM). This technique includes the fabrication of the steel structure, casting the bridge, launching the bridge etc, which are highly repetitive processes and are suitable to be analyzed by simulation. Currently there are many large construction projects taking place in Taiwan, one of which is the high-speed rail project that will connect the major cities of Taiwan. A critical part of this project is the controlling schedule. The objective of this research is to use simulation techniques to analyze the production rate and resource quantity for Taiwan’s high-speed rail projects using FPLM as a construction method. Historical data for pre-cast bridge’s activities were collected and used for checking the probability distributions. In addition, subjective estimation for pre-cast bridge activities using fuzzy number were simulated for the comparison of adopting fitted stochastic distributions. Simulation results show the launching rate for FPLM bridge construction are influenced the pre-cast bridge production construction rate. The results can be used to adjust resources quantities for promoting production rate and decreasing production costs. However, the precision of using fuzzy number for the estimation of pre-cast bridge activities depends on the estimator’s experience. | |||
