摘　　要：应用内外受压厚壁圆筒经典解给出了柱状压密注浆模型(Tresca准则),并且将该模型在各种工况注浆试验及项目实施中检验、修正和提高,同时总结出一些行之有效施工方法,如降低土层强度、土层均匀化等.模型首次给出了柱状压密注浆过程中的应力应变、注浆参数及土层固有力学特性之间关系数学表达式.模型可以在注浆理论研究、注浆项目设计施工中广泛使用.In this paper, a calculation model （ by Tresca rule）for column compaction was deduced from column expansion theory. It was testified, amended and improved in various of grouting tests. A lot of construction methods have been summarized, such as the decrease and uniform of clay. The formulas reflecting the relations among grouting press, grouting radius and grouting stresses and mechanic characteristic of column compaction have been put forward by the model. The model could be used in grouting theory study and design and construction of project.
