本研究自行設計一小型電滲透化學試驗儀，主要針對電滲透化學硬化此一複雜行為，簡化其影響因子（如土壤種類、土樣含水量、電極種類、正負電極間距、電流、電壓、電場分布、通電時間及化學藥劑種類等），嘗試去探討在相同壓密應力的穩定電場中，單一土壤與單一化學藥劑所產生的反應行為和機制，以作為電滲透化學灌漿工法建立一更完整的理論基礎。在減少試驗的影響因子之後，選定氯化鈣(CaCl2)溶液作為化學藥劑，土樣則採用成分單純的高嶺土，並且固定電壓梯度，將氯化鈣溶液由正極端以自重方式灌入；之後持續調整氯化鈣溶液的當量濃度和用量體積，探討其對土壤改良成效的影響。
研究結果顯示氯化鈣溶液相當於電解質，將使得試驗初期之土壤導電性和陰極排水速率增加。氯化鈣溶液之濃度越高、用量越多，即表示鈣離子當量數越多，將使得改良強度和改良範圍越大。但同時也將增加負極端產生沈澱物的速率和厚度，使排水路徑更容易阻塞。然而正極區和中間區的孔隙水被電場帶到負極，但因排水路徑已經阻塞，使得孔隙水無法被排出土壤外，只能一直累積在負極區，導致負極區之含水量始終居高不下，其改良強度自然無法提升。

An electroosmotic chemical cell is developed to investigate the factors affecting electroosmosis chemical hardening behavior and to study the mechanism between soil and chemical solution in a stable electric field. A series of laboratory tests on grouting calcium chloride (CaCl2) into kaoline from anode by gravity is performed. Then, by treating the different concentration and volume of calcium chloride, an investigation on the soil improvement effectiveness was performed.
The result of this study indicates that calcium chloride solution is like one kind of electrolyte and able to increase the soil conductivity and the rate of electroosmotic drainage. Although the soil improvement strength and area are increased with the concentration and volume of calcium chloride, the productive rate and thickness of deposition in cathode zone also increase with them and make the path of electroosmotic drainage clogged easily. Then, the pore water can not be drained out of the soil sample and can only be accumulated in cathode zone. The water content near cathode zone is very high, which makes the improvement strength of cathode zone does not increase at all.
