- 摘要:
- DHT土壤凝合素具有很强的耐候性、耐久性、适用性。在东明石化集团公司120万t/a高硫重油综合利用项目厂区道路施工过程中，广泛应用土壤凝合素拌合黏土、砂土来代替原设计的3：7路基灰土层。通过试验发现DHT土壤凝合素拌合掺量为8%时既能满足路基设计强度要求，且有较好的经济效益。道路投入使用一年来，经过大型载重汽车和450t大型吊车碾压，未出现任何路面开裂和路基下沉现象，证明这种新的施工方法可广泛应用于道路施工中。
DHT soil solidifying agent possesses strong weatherability,durability and applicability.In the 120×104 t/a high sulphur heavy oil synthetic utilization project of Dongming Petrochemical Co.,DHT soil solidifying agent is widely used in road construction in the plant area by mixing it with clay and sand for replacing original designed 3∶7 lime-soil roadbed.The test results indicate that when the mixed ratio of DHT soil solidifying agent is 8%,the roadbed has not only the designed strength,but also the better economic benefit.The roads have been built in the plant for one year,bearing heavy trucks and 450t crane,there has been no any road pavement crack or subsidence happened,which proves that this new road construction technique can be used in other road construction.2010,4(4): 79-80 收稿日期：2009-4-13分类号：U414.2作者简介：龙永新（1968-），男，湖北鄂州人，工程师，1989年毕业于江汉石油学院工业与民用建筑专业，现从事工程技术管理工作。
