摘要
为解决广州南沙地区河涌整治过程中淤泥出路难和筑堤、修路缺土的矛盾,在乌洲涌堤防建设中进行了淤泥固化筑堤试验。试验中,引进了淤泥固化新技术,这是一种在淤泥中掺入固化材料使之发生化学反应,短时间内能让淤泥强度提高的一种技术。选择了乌洲涌整治工程中一段30 m的堤防作为试验段,经过对干密度、无侧限抗压强度、抗剪强度、地基承载力、沉降、渗透性等参数的原型检测,取得了许多有价值的成果,对今后推广应用有一定的参考意义。
In order to solve the contradiction of silt-mud storage difficulty in river harnessing and insufficient soil sources in road construction,the test of silt-mud solidification for levee construction was carried out in the Wuzhou river levee construction.In the test,the new silt-mud solidification technology was introduced.This technology is to mix solidification material in silt-mud to change its physical featues and increase silt-mud strength in a short time.In the Wuzhou river harnessing,a 30 m levee was selected as test section,through prototype parameters check such as dry density,unconfined compression strength,shear strength,bearing pressure of foundation,sedimentation,seepage etc.,some valuable achievements were obtained,which can be referred in this technology application and dissemination.
