中文摘要 | 南化水庫集水區內,由於水庫興建淹沒原有之關山產業道路,重新闢建179線道路工程所產生廢棄土砂,置於公路局沿路設24處廢土場內。本研究係以水庫集水區內各工程棄土區為調查研究重點,並選定179線10k+230m之一處廢土場為試驗區,進行工程廢棄土砂基本力學特性試驗,及其精夯實後再利用之研究。本研究內容係包括野外調查試驗、室內試驗分析及應用地理資訊系統/全球衛星定位系(GIS/GPS)進行調查取得各項資料。野外調查涵括試驗區之地質調查、工地密度試驗及現地棄土砂粒徑分析;室內試驗則包括夯實、壓密、直剪及三軸等各項土壤力學特性試驗分析;GIS/GPS之整合科技主要應用於各棄土場之定位及該水庫集水區邊界的劃定和各相關基本資料之建立。其中棄土砂夯實試驗乃使用美國材料協會所研訂之ASTM D698-A或AASHTO之T99-A規範,以決定不同相對夯實度之重模試體,進而模擬求得不同夯實度時之棄土砂力學特性,根據工程土壤分類研判可作為土壩壩體材料、道路路基及填土路堤等三種利用類型,再根據三種利用模式所需之考慮因素,研訂其現地施工夯實標準,作為本省西南部泥岩區棄土砂穩定處理及合理再利用之施工參考。 |
英文摘要 | In watershed of Nan-Hwa reservoir, the Road 179 was constructed to replace the Kaun-Shan Road which was submerged in the water after construction of the reservoir. Along Road 179, 24 disposal fields of waste soil were assigned. The research focused on investigating the characteristics of these disposal fields. The field located on 10k+230 on 179 Road was the main area to study characteristics of the waste soils and its feasibility of reutilization. Investigation in the study mainly included field investigation, were held in the fields. Compaction test, consolidation test, direct shear test, and fundamental soil characteristics measurement were performed in laboratory. GPS/GIS technology was use to allocate the fields and establish database system of the reservoir. The compaction tests performed under the regulation of ASTM D698-Aand AASHTO T99-A to gain the soil specimen with different compacting energy. The remolded specimens were then subjected to determine mechanic characteristics of the disposed soil. According to the soil classification, the disposed soil could be used as core of earth dam, pavement subgrade, and embankment. The requirements of compacting based on the usages mentioned above were the tested. The study was hopefully helpful to reutilize and stabilize the disposed soil in the mudstone area in southern Taiwan. |
