塑料排水板水下排水固结原理与工程应用

Consolidation Principle for Underwater Drainage by Plastic Drain Bar and Project Application

塑料排水板作为一种成本低、施工方便、质量易控的软基处理方法,在陆上软基处理中已被广泛应用,取得了良好效果。但对于塑料排水板处理水下软基的排水通道是否畅通、固结排水原理是否相同、固结性状和效果如何,工程界的一些人士总是表示怀疑和困惑。结合某疏港公路工程海上段塑料排水板软基处理设计方案,对塑料排水板水下排水固结的基本原理和工程应用进行探讨。

As a soft roadbed processing method with low cost, convenient has been extconstruction and easy control of quality, the plastic drain bar ensively applied in process of overland soft roadbed and obtained perfect effects. However, some persons in engineering field always show suspicion and confusion for whether the drainage channels for underwater soft roadbed processed by plastic drain bar, the consolidated drainage principles are same or not, how the consolidation properties and effects are. In combination with the design scheme for process of soft roadbed by plastic drain bar on over-sea section of some port dredging highway project, this paper discusses the fundamental principles for underwater drainage by plastic drain bar and its application in projects.
