Description
Summary:碩士 === 國立高雄第一科技大學 === 營建工程研究所 === 99 === The technology of microtunneling was introduced to Taiwan in 1994 for the construction works of Taipei City Government. Few experience and lesson about productivity gained from the related microtunneling work have been scientifically documented.However, productivity data is vital for preparing the construction schedule plan. Focusing on the ∮300m/m microtunneling work, this research collects its on-site production and productivity data and perform the analysis by regression and related statistic technology. Meaningful regression equation that can be used to forecast the productivity of ∮300m/m microtunneling work was derived in this research. Based on the equation, four influencing parameters are found to influence the productivity, which are, (1) length of the pipe, (2) Depth of the pipe, (3) N value, and (4) percentage of the clay contained in the soil. Result of this research may provide useful reference and be used to control and manage the work for engineers working in the similar soil conditions. Key Words:Productivity、Microtunneling work
