超软土的排水固结机理分析

超软土地基加固方法的改进，首先需要深入研究其排水固结机理。通过对相关实验实测资料的分析，作者对超软土固结过程中的孔隙性、渗透性、压缩性、固结特性的变化规律及孔隙水压力消散规律进行了初步探讨，并对这些变化规律中的微观机制进行了分析。结果表明，孔隙性的变化从根本上决定了渗透性、压缩性、固结特性及孔隙水压力消散的变化规律。

Analysis on Mechanism of Drain and Consolidation of Super Soft Soil

The ground treatment method for very soft soil do not satisfy the enineering needs presently. This paper studies the drain and consolidation mechanism for ground treatment method improvement of the super soft soil. It aims to obtain some varying laws of engineering properties during the super soft soil consolidated. By quantities of test data, the varying laws of the porosity, permeability, compressibility, consolidation properties and pore pressure, and their varying micro_mechanism during the seepage and consolidation of super soft soil are initially studied. Some mechanism of permeation and consolidation of super soft soil are ascertained. It concludes that the varying laws of above engineering properties is related each other, and the governing mechanism are the varying laws of the porosity and the pore pressure.
