中文摘要 | 本論文介紹筆者多年來在不連續變形分析法(Discontinuous Deformation Analysis,以下簡稱DDA)應用於節理岩盤工程上所獲得的研究成果,包含有:(1)DDA模擬岩體破裂的原理與相關案例的說明,(2)使用新發展完成之DDA程式模擬巴西試驗(Brazil test)。為了使用DDA進行岩體內部破裂行為的模擬,筆者先完成單一獨立塊體之破裂功能,接著以相同的技術進行次塊體(sub-block)的分析功能,使得塊體內之應力分布得以獲得,因此使得新DDA具有模擬岩體內部之破裂傳遞之功能。接著本論文介紹新DDA在巨觀工程上的分析與應用,包括有落石、冰河之移動、邊坡破壞等案例。最後,將新DDA次塊體的分析功能應用在巴西試驗的應力與裂隙傳遞的分析上,其結果顯示與實驗的量測數據相當吻合。 |
英文摘要 | This paper presents the newly developed research achievements of the DDA (Discontinuous Deformation Analysis) method for engineering in jointed rock masses. The first achievement is to introduce principle of simulating the behavior of rock fracture using DDA and its applications. The second achievement is to conduct the simulation of Brazil test using the newly developed DDA program. In order to simulate the fracture behavior inside a rock masses, the fracturing function of an isolated block was initially developed and then followed by the one of sub-block as a result of the distribution inside the block composed of sub-blocks obtained. The new developed DDA, therefore, is capable of simulating the fracture propagation in rock masses. The analysis and application to the engineering problems including rock-fall, glacier movement, and slope failure using the newly developed DDA program were introduced next. Finally, the newly developed DDA program was also employed to conduct the analysis of stress and crack propagation in rock masses of Brazil test. The analytical results appear good match with the experiment measurements. |
