中文摘要 | 本省西南部泥岩覆蓋地區,過去由於泥岩之特殊物理及化學特性,不利於工程建設而未完全開發,但在可預見的未來,公共建設與開發將趨於頻繁。本研究針對此一趨勢,採取西南部泥岩碎屑進行穩定化處理,以利未來可能之再利用。採用水泥及石灰為穩定劑,配合飛灰對泥岩碎屑加以穩定化處理,可有效改善泥岩之工程性質,包括大幅提高其強度、承載力、及降低其對水之敏感程度。在泥岩中添加5~10%的水泥或10~15%的石灰,夯實後可做產業道路或其它次要道路之路基及基、底層使用,而泥岩與10%~15%之水泥混合,經壓實可用於製作低強度土磚或護坡磚使用。此外,在泥岩與水泥或泥岩與石灰混合物中適度添加飛灰,有助於混合物壓實後之強度發展與耐久性,並可降低處理成本。 |
英文摘要 | The mudstone-covered area in the southwest region of Taiwan is faced with many development projects. Since mudstone has been considered a problematic soil, it is beneficial to find ways of stabilizing mudstone for potential utilization. This study investigates the feasibility of using cement and lime to improve the engineering properties of mudstone. It was found that the addition of 5 to 10% cement or 10 to 15% lime is effective in increasing the strength and bearing capacity and reducing water sensitivity of mudstone. The modified soil can be utilized as an economical construction material for roadbed or subbase construction. Mudstone stabilized with 10 to 15% cement is suitable for making low-strength earth bricks. Also, the addition of fl ash to the mudstone-cement or mudstone-lime mixtures tends to increase the compressive strength and durability of the stabilized material. |
