| 摘 要： | 床沙是在特定的水流泥沙条件下所形成的河床物质.床沙测验工作需要使用专门的床沙采样器对河床床沙进行采样,在不破坏天然河床的情况下采集到具有代表深度的泥沙样品,且样品在采样器上提过程中不丢失.对于深水库区河床泥沙进行采样是目前床沙测验中的一个难题.设计了一种利用火药爆炸驱动的新型深水床沙采样器,从天然河床上采集泥沙样本.研究结果表明,该新型深水床沙采样器适用水深可不受限制,采样深度可调,亦能保证样品的完整性、原状性,较好地解决了深水床沙采集问题,具有良好的推广应用价值.

| Abstract: | Bed material is a material formed at river bed under special flow and sediment.A specialized bed material sampler should be used to collect the sediment samples in representative depth without damaging the structure of natural riverbed.And the samples should not be lost when the sampler is lifted out of water that is a difficult problem in testing the bed material at present.In this case a new type bed material sampler,which is powered by explosive,was designed to sample the sediment along natural riverbed ... |
