| 摘 要： | 新孟河延伸拓浚工程位于京杭运河二级阶地,CS36+950~CS40+200段河道堤防填筑材料选取就近河道的细沙,并以别处开挖③-1层粉质黏土(Q43al)为材料进行黏土包坡处理。文章对黏土包坡施工技术参数、粉质黏土(Q43al)包坡材料试验结果、黏土包坡基面开挖及包坡段土方开挖、铺料及碾压、坡脚处反滤体施工等技术要点进行了分析与探讨,对同类河道工程堤防黏土包坡施工能起到借鉴作用。

| Abstract: | Xinmeng River Extension and Dredging Project is located in the second terrace of the Beijing-Hangzhou Grand Canal. The filling material of the river embankment in the section CS36 + 950 ~ CS40 + 200 is fine sand nearby the river,③-1 layer silty clay (Q43al) is excavated as the material to carry out the clay-clad slope treatment respectively. The technical parameters of clay-clad slope construction,test results of silty clay (Q43al) slope clad material,excavation of clayclad slope foundation surface,slope clad section earth excavation,paving and roller compaction,and the filter construction at the toe of slope and other technical keys are analyzed and discussed,which can be used for reference to the construction of similar river embankment clay slope. |
