中文摘要 | 礫石層材料之力學行為及工程特性,正介於土壤力學與岩石力學研究範疇間之模糊地帶。 於一般工程尺度下,因其具非連續、非等向與非均質之特性,造成礫石層材料之力學及工程行為複 雜,礫石層材料工程分析之主要困難度即源於此。本文以粒狀材料結構學法則之觀點,針對由溪流 作用形成之「顆粒支持」礫石層,詳細探究其力學行為機制,並以微觀角度考量礫石層材料之力學 行為及工程特性,同時對於礫石層之微觀與巨觀工程分析法、力學試驗及參數決定方法作一比較。 最後則對顆粒材料微觀力學應用於顆粒支持礫石層作一探討。 |
英文摘要 | The mechanical and engineering behaviors of gravelly soil are complex due to its discontinuous, anisotropic, and heterogeneous nature. This paper studies the characteristics and mechanical mechanism of gravelly soils from microscopic point of view. The main content focuses on the mechanism of clast- supported materials in order to enhance the understanding of the engineering behavior of gravelly formation deposited in the field. Furthermore, this paper discusses the engineering analysis method ( from both micro and macro points of view ) , in-situ or laboratory testing methods and parameter evaluation concerning gravelly formation. Finally, the application of micromechanical model to the gravelly soils is discussed. |
