碩士 / 國立中央大學 / 土木工程研究所 / 94 / The sewage system has become an indispensable public works. Its function has gradually evolved from its traditional goals to having multi-purpose benefits; it not only elevates the feasibility of water recycling, but is also listed by advanced countries as an important indicator of the urban environment. It is an indispensable public works in the modern city, and has the functions of elevating the culture of living and improving the water environmental aesthetic.
Sewage pipe network engineering usually uses tunnel jacking construction method, which is widely used and replaced the traditional open cut dredging method. The pipe jacking construction of sewage pipe network engineering is all conducted underground. If on-site conditions are unclear, the risk factors upon construction cannot be overlooked. Such risks should be analyzed and managed. The main effects caused by construction risks are “cost” and “progress.” A detailed consideration of the influence of risk factors on progress and cost before construction would be a basis for evaluating the construction budget and the construction period.
This study seeks to explore the various construction uncertainties while constructing a sewage pipe network, and establishes an appropriate risk quantification evaluation model and analysis, in hopes that the results of the risk quantification evaluation model can be used as a basis of reference upon establishing the construction budget and period. This method reflects the indirect effects caused on budget and construction period on the practically executed budget and construction period, so that the actual budget and construction period become reasonable. After systematic summarization and organization, this study divides construction uncertainty factors into five main aspects and fourteen sub-aspects of factors. It uses the quantification evaluation model established by this study in expert questionnaires for main sponsors of construction, engineering consulting firms, and professional construction companies to make assessments on the chances of occurrence of risk factors and impacts on losses, and calculates risk values as a reference basis for future studies relating to risk management strategies.
