Remaining objects are unearthed from the wreck as well as the silt above it and the river strata beneath the ship bottom. Those from the wreck and the silt include porcelain (tricolor water droppers,basins, square pots, jars and bowls), pottery (glazed bowls, basins and vessel covers) and a coin (kai yuan tong bao) . Among those from beneath the ship bottom are also porcelain (basins, vessel covers,and bowls), glazed pottery and coins, as well as bamboo mats and wicker baskets. According to the features of the objects from the wreck and the dates of the coins, the ship must be assigned to the Tang period.展开更多
文摘针对古沉船整体打捞工程,利用分布式光纤传感技术替代常规的变形监测手段,在“端板-纵梁”框架整体下放过程中对纵梁和端板进行变形监测.监测结果表明:“端板-纵梁”下放全过程中,端板的变形控制在1.5 mm内,变形量可以忽略;受定位桩与“端板-纵梁”间摩擦力的影响,纵梁最大变形量为50 mm;对定位桩打磨切割可有效减小纵梁变形量,纵梁最终变形量约为35 mm.
