浅层真空预压法在太湖疏浚淤泥固化中的应用

Application of Shallow Vacuum Preloading to Taihu Dredged Sludge

对湖泊疏浚淤泥进行固化处理,防止其产生二次污染是目前生态治理湖泊中的一个重要内容。引入浅层真空预压法对太湖疏浚淤泥进行固化处理,对施工过程中沉降、孔压、真空度、十字板剪切强度、载荷板等监、检测数据进行了分析,结果表明该方法能够对太湖疏浚淤泥进行快速处理,施工方便,加固效果能够满足设计要求。

Solidification of the lake dredged sludge and preventing it from secondary pollution is one of the important aspects of the ecological management of lake at present.The shallow vacuum preloading method used in the reclamation engineering is introduced to solidify the Taihu dredged sludge for the first time.During the solidification process,the surface settlement,vacuum pressure,pore pressure,vane shear strength were monitored and the static load test data were analyzed.The results show that this method is able to consolidate the Taihu dredged sludge quickly and cost effectively.
