Summary: | 碩士 === 逢甲大學 === 環境資訊科技碩士學位學程 === 97 === The Global Position System (GPS) has been widely applied to monitor the crustal movements for a long time due to its high precision and independence of meteorological conditions.After In 921 Earthquake caused a great landslide at the north of Ping Ding Activity Center and the south bank of Linbei Keng.
Ping Ding landslide is in the mountain area of eastern Linnei Township, Yunlin County. Linnei is located in northeastern Yunlin County and is adjacent to Mt. Ping Ding, Ping Ding village and Jhushan Township, the land at the source of Linbei Keng (Ping Ding River) will collapse when there is rain or an earthquake. Leica GMX901 Satellite positioning single-frequency, continuous observation (08 years in August to November, four months) of satellite data, the coordinate changes in the accuracy of assessment and analysis, accuracy assessment of the baseline variables and baseline analysis, deformation analysis, results for the:1. To the five GPS stations (E, N, H) coordinates, in which (E, N) coordinates of the standard error of 1 cm, height H of the standard error for the 2.3 cm, u-test to test, During this period there was no significant displacement coordinates. 2.The 5 GPS base station to station there was no significant change in the baseline. 3. To the five GPS stations of the network posed by the overall deformation of shape analysis to test t-test to determine "Ping Ding Village" in the meantime there is no significant deformation.
