摘要
以大滩口水库坝前淤泥面上利用加坝自重形成堆载,对水库淤积层进行预压固结为例,针对库区淤积物这类饱和软土具有高压缩性、高灵敏度、高流变性和低强度、低渗透系数的工程特性,借助堆载预压地基处理计算理论,进行坝前淤泥面上加固设计,探求加固机理,制定加荷计划,为类似工程设计及安全施工起到了重要的指导作用。
Taking the preloading consolidation on the sludge before the dam of Datankou Reservoir by using the selfweight of increasing the dam height to form the piled load for example, and aiming at the engineering characteristics of the saturated soft soil in reservoir area such as the high compression, high sensitivity, high-rheologic behavior and low strength, low permeability, etc. , the reinforcing design on the surface of sludge before dam is made by using the theoretical caculations for the piled-load preloading and subgrade treatment, so as to research on the reinforcing mechanism and loading plan, which may provide the important guidance for the design and construction of other similar projects.
