| 為探討小斷面灌溉隧道之施工效率，本研究延續林正忠之論文，以完整的能高大圳隧道工程資料為案例，從施工輪進紀錄之分析，整理出影響進度之因素，並針對效率問題提出有效的改善方案，期將能高大圳隧道的開鑿資料供工程界參考。 經現場開鑿後可知，本工址岩體分類以第Ⅲ類及第Ⅳ類岩體為主，佔本工程的百分比達98.42%，岩體的一致性相當高。各類岩體開挖每公尺平均所需時間以第Ⅱ類岩體最短，第Ⅲ岩體次之，第Ⅳ類岩體最長，呈現岩體條件越差所需耗費之時間愈長。各類岩體之開挖時間以鑽孔所占比例最高，其次則為噴凝土，第三則是出碴及岩栓打設。就本工程鑽孔時間而言，第Ⅱ類岩體每公尺所需時間最短，第Ⅳ岩體次之，第Ⅲ類岩體最長，歸責原因為第Ⅱ類岩體屬於厚層變質砂岩，岩質較第Ⅲ、Ⅳ岩體均質且完整，因此鑽孔時夾桿情況較少。 為節省支撐系統作業時間，岩栓每2~7輪才合併打設一次，符合Bieniawski 氏免支撐時間的安全範圍內，且實施後未對隧道穩定性產生影響。工作之編組為順應工程界以實作數量計價的習慣由全能輪進班改回專業分班，雖不符目前潮流，但經研究發現，此分班方式對於小斷面隧道施工效率並無降低之情況。工程閒置時間以機具故障所佔比例最高，而601型鑽機的損壞又占首位。 |

| To investigate the construction efficiency of a small irrigating tunnel, this study continued the thesis written by Lin, the aim was on the complete construction of a tunnel for Neng-Gao canal, the focus was on tunneling round to analyze influencing items of tunneling, and then this research proposed the improving ways on working efficiency. Therefore, the history of tunneling on Neng-Gao canal was recorded by this research, and provided for construction and design engineers. It can be seen after tunneling, most of in-situ rock can be classified as Type-III and Type-IV, which dominate 98.42% of in-situ rock types and are very consistence. It was found, the shortest tunneling time per meter is in Type-II rock, the following is in Type-III, and the longest is in Type-IV; the weaken the geological condition, the longer the rounding time. According to the statistical results, the orders of time consumption are the drilling, the shotcrete, the outing derbies, and the rock bolting, which dominate main construction time. The rock more weak, the drilling time more long, this phenomena is resulted from the fewer squeezes on drilling rod by Type-II rock. To reduce the constructing time, rock bolts were installed every 2-7 rounds. This way meets the safety range of un-support which proposed by Bieniawski. Furthermore, there is no evident effect after executing this way. A general squad was applied initially; it was changed into several professional divisions due to the engineering custom of counting price by working quantities. However, the efficiency of professional divisions was as well as a general squad in this study. It can be seen from the statistical analyses, the idleness results from machines unavailable mainly, a damaged 601-Type drilling machine is the main cause. |
