中文摘要 | 本研究旨在探討土壤抗剪與根系補強之關係,藉由根系與土壤間之彈性變形、滑移作用與斷裂現象來反應土壤之力學行為。為確認分析方法之正確性,本文取文獻中已有測試實例,大麥為主要研究對象。研究中發現根系補強對於飽和黏質壤土抗剪強度之貢獻在於握裏滑移而非斷裂現象。據此,為增加土壤抗剪強度,有建議植生工法應考慮種植適合現場環境生長及能深入土層之草本植物。 |
英文摘要 | In this study, we aim to find the relation between the soil’s shear resistance and root mechanical reinforcement. Root-soil mechanical behavior will respond to the loading by root stretching, root slipping, and root breaking. In order to verify the correctness of the analytical methods, the data of experiments of barley available in literature was used. From the analytical solutions of the root-soil mechanical method, we find the main effect of the root reinforcement in saturated fine-textured soil is the strength of the soil-root bound rather than root breaking. With a view to increasing the shear strength of the soil, the grassed plants, which can be deep-rooted in soil and suitable for planting in domestic climate and the environment, is recommended for ecology engineering in this study. |
