| Popis: | 102 National Yang-Ming University for domestic unique development along the hillside campus, Since the campus is a bit hillside, Safe slope, related to the safety of the school''s teachers and students, as well as the protection of premises, so for the sliding slope campus must monitor their safety and changes in circumstances, for the state of emergency at the time of the occurrence, to get advance warning, and thus can be handled expeditiously, in order to maintain the safety of students and teachers. Campus slope failure is mainly due to massive rain down, followed by campus environment can not be effectively drained. this study tries from concentrate or high-intensity rainfall, rain delay, drainage and groundwater can not effectively dissipate and reduce to explore, I hope with the greatest rainfall intensity and accumulated rainfall amount effective to develop warning value and action value, used as a campus slope monitoring and management, very quickly and easily rainfall information from the judge. there is also hope that the situation changes from rainfall and groundwater levels, and relationships dissipate drainage and time delay, develop warning value of another slope monitoring management indicators as his assistant. The results of this study show that when the maximum rainfall intensity of 76 mm / hr, the effective amount of accumulated rainfall reached 824 mm, the campus of slope failure that may occur, may use this as a warning value slope monitoring management; when the maximum rainfall intensity at 46 mm / hr, the effective amount of accumulated rainfall in 630 mm, seems in danger of slope failure occurs, may use this as a warning value slope monitoring management. another case of rainfall and groundwater level changes, and dissipate drainage and time delay time there is a correlation, this study can set a warning value slope monitoring management, To build the campus of M-1, M-2 and M-3 and other three stations, the amount of change in the groundwater level in the case of each station long duration rainfall (greater than 50 hours) of rainfall during the analysis, M-1 where the water level changes in the station''s warning value is 9M, M-2 where the water level changes in the station''s warning value is 10M, M-3 where the water level changes in the station''s warning value is 7M; the other end point in time before the rain event, the water level began to decline, the amount of the difference between the change in water level will gradually decrease, representing the water level gradually decreased,where M-1 station in rain delay to set the warning value is 111 hours, M-2 station in rain delay to set the warning value is 111 hours, M-3 station in rain delay to set the warning value is 120 hours. |
