碩士 === 國立臺灣科技大學 === 營建工程系 === 93 === The construction of tunnels becomes one of the most important engineering construction in our country. As wolds share one third of Taiwan Island, therefore, the construction of tunnels cannot be neglected, so as to improve the transportation. However, the balance of rock layers and water pressure will be destroyed during the process of digging rock tunnels, some of the groundwater will well out as the rock layer is rich in water. The pollution caused by the constructive work will turn the groundwater into turbid water, then it will become wastewater which contain a high degree of suspended solid and alkali. If the wastewater has not been treated properly, it will be drained from the tunnel to nearby lakes and rivers, and will cause environmental pollution. The failure in treating the wastewater was mainly due to the following reasons: The sewage plant is lacking in the investigation of the source, maintenance of manage system, the experience in dealing urgent cases etc. According to the problems mentioned from the above, we will investigate the technique of date mining by using Hsuehshan Tunnel as an example, in order to build up the experience in predicting the quantity and quality of the wastewater. This project is intended for sewage plant as a reference. It timed the maintenance of the system, provided concentration of suspended solid so as to make proper use of PAC, predicted the occurrence of the well up groundwater. To prevent environmental pollutions, the wastewater caused by the construction of tunnels should be treated properly before drain it away. This project was set up with the aim of achieving this goal.
