海湾的自然条件(包括水文、气象和地质地貌等)与港口建设和发展有着极为密切的关系。因此,为了正确地选择港址,合理地进行港口规划和总体布局,确定合适的建筑物型式及施工方法,对建港地区的各种自然条件要有充分的了解。然而,对自然条件的调查研究,是港口建设的第一步。 其中,在建港地区进行的地质调查中,主要包括地质构造、基岩埋深、岩层(包括松散岩层)的分布情况、土质的物理力学性质等内容。为了解决这些问题,常常采用钻探取样来获取资料。然而,在水上钻探中,存在着费用昂贵和时间长等问题。近年来,国内外采用浅地 The natural conditions of the Gulf (including hydrology, meteorology and geomorphology, etc.) are closely related to the construction and development of the port. Therefore, in order to properly select the port, make reasonable port planning and overall layout, and determine the appropriate building types and construction methods, we should fully understand the various natural conditions of the port of entry. However, the investigation of the natural conditions is the first step in port construction. Among them, the geological survey carried out in the Hong Kong-built area mainly includes the geological structure, the bedrock depth, the distribution of rock formations (including loose rock formations) and the physical and mechanical properties of the soil. To solve these problems, drilling sampling is often used to obtain data. However, in water drilling, there are problems such as being expensive and time-consuming. In recent years, shallow to adopt at home and abroad
