土石坝的施工方法分为干填碾压(碾压式)、水中填土、水力充填(包括水坠坝)和定向爆破修筑等类型,本案例工程采用碾压式填筑。随着机械化程度的提高,大容量的土石方设备运用到施工中,填筑材料适用范围的拓展,原来不适合作坝料的材料也可作为填筑料,从而为碾压式土石坝的施工创造了条件。文章以某新建水库工程为例,介绍均质土坝工程填筑技术。并探讨了填筑原理、施工工艺及质量控制措施。
Earth-rock dam construction methods are divided into dry-filling rolling (roller compaction), fill in the water, hydraulic filling (including water crashed dam) and directional blasting construction and other types. The case project uses roller compaction. With the improvement of the degree of mechanization, large-capacity earthwork equipment is applied to the construction, the expansion of the applicable scope of the filling material, the original material unsuitable for the dam material can also be used as the filling material, thus creating the construction of the roller compacted earth-rock dam condition. Taking a new reservoir project as an example, this article introduces homogeneous earth dam construction technology. And discusses the principle of filling, construction technology and quality control measures.
