Description
Summary:碩士 === 國立成功大學 === 土木工程學系碩士在職專班 === 103 === This study used data from deep excavation cases of sedimentary geology, aggregate analysis of drilling and monitoring, and other relevant data in Tainan to find the relationship between ground settlement caused by deep excavation and retaining wall deformation. According to the studies of Peck (1969), Clough and O'Rourke (1990), and Hsieh and Ou (1998), in order to successfully predict ground settlement in Tainan, it is necessary to find Tainan’s ground settlement curve distribution. Statistical analysis showed that the maximum lateral yielding ranges from 0.05% to 0.2% of the excavation depth. Ground settlement distribution curve proposed by Peck (1969) overestimated the ground settlement in Tainan, while Ou and Hsieh’s method estimated a maximum value of ground settlement that is 0.2 to 0.75 times the maximum lateral displacement value. The results of Clough and O’Rourke’s method, on the other hand, ignored the settlement of the secondary influence zone, and the maximum ground settlement value ranged from 0.35 to 1.0 times the lateral yielding value.
