摘　　要：井阻和涂抹作用是采用塑料排水板进行排水固结地基处理过程中普遍存在的现象,对地基固结度影响较大。具体阐述了涂抹和井阻作用产生的机理和对地基固结的影响,分析了涂抹影响因子和井阻影响因子的计算方法,指出了各种计算方法的区别,并分析其合理性,从而为排水固结地基处理的分析和设计提供了参考。Well-obstruction and daub-effect are often met in the process of consolidation by prefabricated drains for ground improvement and their influences on the degree of consolidation are great. This paper expounds the principle of well-obstruction and daub-effect and the influence to foundation consolidation, analyzes the calculation methods of factors concerning well-obstruction and daub-effect, and points out the differences between these calculation methods and analyzes the rationality of the methods. It provides a reference for the analysis and design of drainage consolidation of foundation improvement.
