摘要

本研究設計模擬滲透灌漿技術之實驗室設備進行試驗砂柱之灌注試驗，以渥太華標準砂依不同比例配製成8種不同粒徑分佈之試驗砂柱，再以市面上常用之3種不同基質進行灌注。由灌注試驗結果顯示，當試驗砂粒徑越大、基質黏滯度越小，則灌注效果越好；若試驗砂含5%以上之細料則對灌注結果有明顯影響。
36組滲透灌注試驗結果以Spearman等級相關係數計算及參數廻歸，得到試驗砂有效粒徑(D10)與基質黏滯度(μ)對灌注高度、灌注時間及流失率之關係式。研究結果對於擬應用滲透灌漿技術於地下水現地生物整治，在現場進行中細砂地層基質灌注試驗提供可預測性之灌注結果。

This study design the sand column tests in the laboratory to evaluate permeability and efficiency of substrates by using permeation grouting technology. The results show, the coarser the test sand and the lower the substrates viscosity, the better the grouting effect. If more than 5% fines added will affect the grouting results significantly. Spearman’s rank correlation coefficient and stepwise regression method were applied to analysis 36 sets of sand columns testing results. The relationships among the effective size of test sand (D10), the viscosity of substrates (μ)and grouting height, grouting time, grouting rate and outflow rate were obtained. The results of this study might be helpful for applying the permeation grouting technology to remedy the contaminated groundwater in the field.
