摘要
膨胀土因在形貌上和工程性质上的特殊作用和破坏作用的严重性,引起了广泛的重视。为消除、减小膨胀土危害,提高其工程适用性,人们采取了许多处理方法,改性膨胀土由于具有较好的性价比而受到重视。通过对各种改性膨胀土的现状分析,探讨了其固化机理及影响膨胀土的胀缩性能、强度等诸多因素,并对下一步膨胀土改良进行了展望。
Much attention on the characteristics and morphology and the use of the expansive soil has been paid because of the special engineering damage effects as well. Many methods have been used to reduce the damage effects and improve the application of expensive soil during recent years. One of the effective methods is the modified measure due to the ratio of cost-performance. The major factors affecting the expansive-shrinkage performance and the strength were discussed through all kinds of the modified expansive soil＇s status in quo. Recent research work on the chemical consolidation of expensive soil was reviewed in the paper.
