为摸索黄河河口游荡摆动规律和油田建设的需要,长期、连续的潮汐观测是必要的。针对黄河三角洲滨海区是泥沙淤积的沙土质海岸,其海岸带坡度小、滩涂广阔潮下带水浅,且海岸随河口的摆动,或向海淤进,或受潮流和海浪作用而蚀退,因此,只有在潮下带水域才能设立观测站。此外,滨海地区冬季流冰、封冻,汛期漂浮物众多,狂暴雨又为常事。因此设立的观测设备必须经得起撞击、缠绕、封冻等,而不倾不倒。我们分析了以往滨海水域木质三角架经不起大风大浪冲击的教训,又调查了利用废油井
In order to explore the law of wandering and swinging of the Yellow River estuary and the need of oilfield construction, long-term and continuous tide observation is necessary. For the coastal area of the Yellow River Delta, there is a sediment-laden sandy coast with a small gradient on the coastal zone, a shallow tidal flank with shallow tidal flats, and a coastline swirling along the estuary or silting in the sea, or eroded by currents and waves Therefore, an observatory can be set up only in subtidal waters. In addition, the winter coastal ice, frozen, many floats in the flood season, violent rain is commonplace. Therefore, the observation equipment set up must be able to stand up to impacts, wind, freeze, etc. without dumping. We have analyzed the past coastal wooden tripod can not withstand the impact of strong winds and waves of the lessons, but also investigated the use of waste oil wells
