摘　　要：海上静力触探是一种操作简单、经济高效、测量数据可靠的海床土体原位测量方法。国内自主研发的海上静力触探设备很少能够广泛的应用在实际工程勘察中。本文介绍了一种新型海上静力触探设备,由贯入系统、液压系统、甲板控制系统、浮力系统四部分组成,可在地形复杂多样的滩浅海区域进行连续走航测试。利用这套设备在黄河口海域进行地质勘察,并对该海域的海床土层结构划分进行了探讨,证明了该设备在滩浅海地区的工程勘察领域有者广阔的应用前景。Offshore cone penetration test（CPT）is a method for in-situ measurement of seabed soils,which is simple in operation,cost effective and reliable in measured data.The offshore CPT equipment developed independently in China is rarely able to be widely applied in the practical engineering explorations.Herein,a new offshore CPT equipment is introduced.This type of equitment consists of penetration system,hydraulic system,deck control system and buoyancy system,and can make exploration continuously in navigation in the beach and shallow areas with compex topography.This set of equipment has been applied for a geological survey in the Yellow River delta area,by which the structures of subbottom sediments are divided and discussed,indicating that the equipment has wide potential applications in the field of engineering geologic exploration in the beach and shallow sea areas.
