摘要
深厚淤泥基础上修建围堰,整体稳定依赖于淤泥的固结作用。采用插打塑料排水板方法对浓厚淤泥进行排水固结是经济实用手段。以广州港出海航道中疏浚土接纳围堰工程为例,阐述了淤泥力学指标,介绍了设计断面、稳定计算法,施工要求。提出了搞好施工的若干建议。为类似工程设计施工提供了参考。
The overall stability is dependent on the consolidation effect as the cofferdam based on deep silt has been constructed. The inserted plastic drainboard is an economic method for draining and consoling of the deep silt. This paper, taking the cofferdam engineering of the dredged earth receiving area in the navigational channel of the Guangzhou Port, states the mechanical index, introduces the section design, calculating method of stability and constructive demands. Also it puts forward several suggestions for construction.
