摘要註:	根據環保署的統計資料得知，台灣近幾年來將大量的焚化底渣運用到道路相關工程之中，藉以取代掩埋做為最終處理方式，但焚化底渣是一種非常不均質的再生材料，所反應的工程性質也可能會有所差異。面對焚化底渣使用越趨頻繁的現狀，同時也為了確保工程施作之品質，探討其組成差異對相關工程性質之影響便有其必要性存在。本研究蒐集相關焚化底渣再利用及研究相關資料，針對一般工程應用上較少考量的化學性質部分，也就是焚化底渣的主要組成SiO2、CaO、Fe2O3及Al2O3的組成比例進行實驗設計，並以直接剪力試驗探討化學組成對於相關工程性質的影響。最後以統計的概念，透過多變量迴歸分析對直接剪力的實驗結果進行討論，並提出再利用上的相關經驗方程式及建議。研究發現未焚化一般事業廢棄物的焚化底渣，通常是以SiO2為主要組成物質，在乾燥條件下的摩擦角介於48.04°-52.66°之間，依據多變量分析的結果顯示，乾燥條件下摩擦角的改變主要受Fe2O3及Al2O3的影響；在濕潤條件下的摩擦角介於44.16°-54.62°之間，多變量分析結果顯示，濕潤條件下摩擦角的改變主要受CaO及Al2O3的影響。若有處理部分一般事業廢棄物的焚化底渣，Fe2O3及Al2O3常會較高，在乾燥情況下的摩擦角，大致介於44.60°-52.52°，多變量分析結果與未焚燒事業廢棄物之底渣相同，受Fe2O3及Al2O3的影響較多。因此建議在焚化底渣的使用上，能針對影響較大的化學組成進行控制，藉此可以獲得較佳的工程特性，也能確保相關工程之品質。 According to the statistical information of Taiwan’s EPA, in recent years, a large number of bottom ashes are used for the road construction in place of burying it as the final process. As the bottom ashes are used more and more frequently, the effect of different constituents of bottom ash for related engineering plays an important role to make sure the quality of operation. For geotechnical engineering, it is seldom to consider the chemical composition. Therefore, this study focuses on the effect of proportion of the principal constituents in (SiO2, CaO, Fe2O3, and Al2O3) bottom ash on the direct shear test. Additionally, the multi-variable regression analysis is employed analyze the consequence of the direct shear result and to propose an experiences formula. This study discovered that the bottom ash from untreated general industrial waste of incinerator usually takes SiO2 as the main component. In dry condition, the friction angle is between 48.04° and 52.66°. Based on the result of the multi-variable regression analysis, the friction angle is mainly affected by the Fe2O3 and Al2O3 in dry condition. On the other hand, in the wet condition, the friction angle is between 44.16° and 54.62°, and the friction angle is mainly affected by the CaO and Al2O3. However, when the bottom ash is collected from treating general industrial waste of incinerator, that usually has highly contents of Fe2O3 and Al2O3. In t he dry condition, the friction angle is almost between 44.60° and 52.52°. It the same consequent of the multi-variable regression analysis as non-general industrial waste incineration plant that has deeply affected by Fe2O3 and Al2O3. Therefore, we recommend to control influential chemistry constituents of bottom ash, in order to acquire better engineering property, and to make sure the quality of engineering property.
