| 中文摘要:适航水深资源开发关键技术是如何利用现行水深以下淤泥质回淤层进行通航，以达到增加航深和降低航道维护费用之目的。国内外针对淤泥质港区或呈淤泥特性航道适航回淤层取样技术主要集中在非接触与接触二大类。目前，以荷兰Silas系统为代表的非接触类取样技术已趋于成熟，并在国内外广泛应用；而用于现场回淤层接触类取样技术至今尚未取得显著突破。工程实践中，需对非接触类技术获取的取样数据进行验证。研发一种具有稳定、高效的原状淤泥性土取土器，丰富并完善这一领域接触类取样手段，具有现实意义。 |

| Abstract:The key development technology of nautical depth is how to use the silty back silting layer under current water depth as navigation channel in order to increase the navigation depth and reduce the maintenance costs. The sampling technique used in silty harbor or the silt characteristics nautical back silting layer is mainly devided into categries of non-contact detection and contact sampling both in China and abroad. At present, the non-contact detection technique represented by Dutch Silas system has been mature, which has been widely applied worldwide; while there is no significant breakthrough in contact detection technique in back silting layer. In engineering practice, the detection data by non-contact technique should be verified. It is necessary to develop a stable and efficient sampler for undisturbed silty soil sampling and the contact sampling technique should be enriched and perfected. |
