碩士 === 國立中央大學 === 土木工程學系碩士在職專班 === 97 === Abstract For contractor，it is the big problem to resolve the water-logged from the structure-underground(for example, the subway tunnels) after finishing work. Because the reasons：Water is the biggest factor will destroy the safety of the structure of tunnel for a long time usage. So many methods were being created to resolve this problem, no matter a lot of money or efforts will be invested. The traditional methods, they usually put the concert into the waterproof such as the surface to prevent the water-logged speed out. But in fact, it is no effective and waste money. And when waterproof was out of functions, it costs a lot of money to fixed. This is the most important reason why I will try to find out the better methods to resolve the water-logged problems and reduce the cost in maintain the tunnel- structures. This is my core hypothesis：Watertight Concrete in prevent the water-logged will be better than traditional methods. My case study is the “Nangang CL306/391A Siangyang Rd.” tunnel and common duct engineering. I focus on three demotions: the Watertight Concrete design、material and working process. How to improve water-logging methods and making the new big process in preventing water-logged are my final purposes. In my research, I set up two samples(experiment & compared), and then compare the low permeability of this two samples. According to my result, I find that the experienced item which composed in Watertight Concrete elements could prevent water better than compared item. And I follow the standard procedure of Watertight Concrete. It could be more effective in preventing water and resolving the water-logged from the structure-underground. So I proof the Watertight Concrete is indeed the better choice for the tunnel engineering.
