摘    要：由于氯化钙会与土壤络合产生胶结和硅 化，作者选择了表面活性剂丁二酸钠作为助渗剂，采用试验方法测定了在氯化钙溶液中添加该助渗剂后在粉尘中的渗透行为．试验结果表明，合适的丁二酸钠添加量 可在一定程度上提高氯化钙溶液的渗透能力和降低溶液的表面张力；对于浓度为5%，15%，25%(质量分数)的CaCl₂溶液，丁二酸钠的适宜添加量分别 为0.2%～0.5%，0.2%～0.3%，0.2%～0.3%(质量分数)，此时溶液的渗透能力可分别提高约18%，14%，13%．这一研究结果对用 氯化钙固土抑尘具有积极作用．

Abstract: Since calcium chloride solution can cement and silicify soil, this principle is often applied in soil stabilization for unpaved road and base and dust raising control. In this paper, a surfactant named sodium succinate was selected as a penetration ability aiding agent of calcium chloride solution. Accordingly, the penetration performance of calcium chloride solution after adding the agent in dusts was investigated by means of experiments. The results show that sodium succinate can increase the penetration ability of calcium chloride solution and decrease its surface tension to some extent. For the solutions of calcium chloride with 5%, 15% and 25% concentrations, the suitable adding quantity of sodium succinate is 0.2%～0.5%, 0.2%～0.3% and 0.2%～0.3% respectively, and the increment of penetration ability is 18%, 14% and 13% respectively. These results are significant for calcium chloride solution to be used in soil and dust stabilization.
