    Abstract: 本研究使用有限元素方法,進行單樁基礎因降低地下水所引致的行為研究與分析。在軸對稱的假設下,並採用Mohr-Coulomb準則,對於單樁基礎因水壓的變化所產生的土壤沈陷與樁身表面之摩擦力進行相關的研究。研究內容主要包括地表沈陷、樁身摩擦力與樁之軸向力等研究。數值分析的結果將與單樁離心模型之試驗結果進行比較與驗證。由於試驗一般不容易對單一變數的影響效應進行觀測,因此藉由數值分析的變數控制可以補足試驗結果的不足,兩者分析結果的比較應能進一步作為將來工程運用與設計之參考。 In this thesis, elastoplastic finite element method is applied to analyze the behavior caused by single pile foundation in soft clay. Axisymmetric eight node rectangular elements are adopted and the Mohr-Coulomb criterion is used for simulating the elastoplastic stress-strain behavior. The lowering of the groundwater induces the settlement of the soil. This research focuses on the settlement of the ground and the skin friction of soil around pile. The numerical results are expressed in terms of schematic figures. The results are compared with those from centrifuge model test.
