黄河丁坝土工织物软体排的施工技术分析

Analysis on Construction Technique of Yellow River T-dam Geotextile Soft Mattress

分析了黄河丁坝防护工程的土工织物软体排的施工技术,排体的布置范围、分块搭接与坝前冲刷坑的形状、深度、大小有一定的关系。软体排的平面尺寸取决于坝前冲刷坑的最终稳定深度和坡度。进行了冲刷坑深度、软体排的长和宽的计算,探讨了丁坝软体排的布置方式及排体的分块和搭接工艺。

It analyzes and finds out that the geotextile soft mattress construction techniques, layout range and block-overlap of the Yellow River T-dam protective engineering have certain relations with the shape,depth and size of scour pit in front of the T-dam. The plane dimension of soft mattress depends on the ultimately stable depth and slope of scour pit in front of the T-dam. The depth of the scour pit and the length and width of soft mattress have been calculated, as well as the soft mattress layout form and blockoverlap techniques of the mattress body have been discussed.
