| dc.description.abstract | 本研究針對潛盾隧道開挖時所使用之冰凍工法，進行其凍脹行為的熱應變數值分析，模擬的案例為國立雲林科技大學校址內進行的冰凍開挖試驗，依照試驗現地狀況建立有限元素數值模型。在力學分析中，將熱傳導數值模擬所得之溫度分佈場視為熱載重，並適當簡化有限元素模型，使其成為更適合力學分析模擬。研究中使用有限元素軟體ABAQUS進行熱應力分析，以此模擬冰凍試驗之程序及方法，分析土壤之凍脹行為。 | zh_TW |
| dc.description.abstract | The main objective of this study is to analyze the thermal strain and the behavior of ground process frost heave for freezing method applied to tunnel construction. The simulated case is the ground freezing test carried out in National Yunlin University of Science and Technology. A finite element simulation model has been established according to in-situ condition with the temperature distribution of the heat transfer as the thermal loading. Additionally, a simplified mechanical model was established and applied to mechanical analysis in this study. The computer package ABAQUS is used for thermal stress analysis to study the behavior of frost heave of frozen soil. | en_US |
