摘　　要：我国广泛分布着软土,软土加固处理是一个重要的岩土工程问题.软土主要是由碎屑黏粒和黏粒混合构成的一种具有复杂的胶体化学和电化学性质的黏性土.目前,软土的加固处理方法主要是机械或物理的方法,外加固化剂以及电化学方法虽然也有过一定研究和实践,但仍有许多理论和技术环节需要探讨和研究.故特对软土的胶体化学与电化学性质进行了分析,探讨了利用软土的胶体化学与电化学性质进行软土加固的问题.China＇s extensive distribution of soft clay, soft soil reinforcement is an important geotechnical problems. Soft soil is clay and debris from the clay mixture consisting of a complex colloid chemistry and electrochemical properties of clay. At present, the reinforcement of soft soil treatment is a major mechanical or physical method, plus curing agent approach, as well as electro-chemical although there were certain research and practice, but there are still many theoretical and technical aspects of the need to explore and research. This paper analyzes the soft soil colloid chemistry and electrochemical properties, to explore the use of the soft soil colloid chemistry and electrochemical properties of soft soil reinforcement.
