碩士 === 國立暨南國際大學 === 土木工程學系 === 100 === The study case of the geosynthetic–reinforced soil wall is located at Road 132 7K+680~7K+780 Maolin District Kaohsiung City. It is 20 meter high with a setback of 6 meter every 5 m high. First before the process of construction, the strain agues was pasted on the selected location of geogrid which will be later placed into the geosynthetic–reinforced soil wall. For the convenience of survey after the construction being completed, the length of signal line is properly decided. Because the strain gauges are likely to be destroyed during construction,the protective measures must be made on the strain agues and signal line in order to prevent the none-reading situation after the construction being completed. The strain figures are read at every 5 meter of the geosynthetic–reinforced soil wall during construction.After construction,the he read will be executed every month, and after the occurrence of earthquake and heavy rainfall. Moreover,the wall face displacement of the MSE wall is also measured.The numerical analysis of this MSE wall is performed by using PLAXIS software. The simulated strain and wall face displacement is compared with the field measurements. The discrepancy between them is discussed.
