在黄河中下游干支流河床新近期形成的冲积层中,由于主流的摆动和水位涨落的影响,广泛分布与水工建筑物地基稳定密切相关的夹泥层。在沁河河口村水库坝址勘探中,对河床砂卵石层中央泥层的分布情况和工程地质性质进行了初步研究。 In the newly formed alluvial layer of the mainstream in the middle and lower reaches of the Yellow River, the mud strata, which is closely related to the foundation stability of hydraulic structures, are widely distributed due to the influence of the main stream swing and water level fluctuation. In the exploration of Hekoukou reservoir dam site in Qinhe, the distribution and engineering geological properties of the central layer of sand and gravel in the river bed were studied.
