摘要:
膨胀土因在形貌和工程性质上的特殊性和破坏作用的严重性,引起了广泛的重视。为消除、减小膨胀土的危害,人们采取了许多处理方法,化学固化由于具有较好的性价比而受到重视。对膨胀土的化学固化现状的分析,探讨了影响膨胀土的胀缩性能的诸多因素,分析了使用现有固化方法固化的膨胀土长期耐久性不良的主要原因。在此基础上,对膨胀土固化的研究思路进行了分析,并对下一步膨胀土固化研究进行了展望。

Much attention on the use of the expansive soil has been paid because of the special engineering characteristics and morphology and the damage effects as well. Many methods have been used to reduce the damage effects caused in the applica-tion of expansive soil during recent years. One of the effective methods is the chemical consolidation due to the better ratio of cost-effectiveness. Recent research work on the chemical consolidation of expansive soil was reviewed in this paper. The major factors affecting the expansion - shrinkage performance were discussed. The failures in the durability of expansive soil consoli-dated by some methods were analyzed. In addition, some aspects on further researches for the chemical consolidation of expan-sive soil were also presented.
