降水联合强夯加固吹填土地基试验研究

本文总结了吹填土地基的工程性质特点,介绍了一种能快速、有效地处理该类地基土的新工法——降水联合强夯法。从该工法的施工工艺、作用原理等方面进行了深入的阐述,并结合某工程进行了现场试验研究。通过分析试验结果得到处理后的地基土有效加固深度、承载力均满足设计要求。分析了地基土沉降过程与影响因素之间的关系,从理论与工程实践两方面验证了该工法处理吹填土地基效果良好。

Experimental study on the treatment of dredger fills by using precipitation and dynamic consolidation

The engineering characteristics of dredger fills are summarized, and a new method-- precipitation united with dynamic consolidation which could treat the soil fast and effectively is introduced. Taking a project as an experiment example, the construction process and working principle of the method are explained. The effective consolidated depth and the bearing capacity of the soil after the treatment could meet the design requirements. The relationship between the settlement process of ground and the influence factors is analyzed, and the good effect of the method is proved both from theory and engineering practice.
