摘　　要：嵌入式混凝土锚体作为系泊设备的主要构件,其提供的锚碇力对工程装备的安全可靠有着极为重要的影响.试验中采用的黄河砂土属于粉细砂,潮湿状态下对嵌入式混凝土锚体吸附力远超过一般砂土.中设计系列试验方案,探究锚碇缩尺比、埋深、形状、拉力角度,以及水饱和度等因素对黄河砂土中混凝土锚体锚碇力的影响.通过模型试验,得到锚碇力系数随各因素的变化规律.Embedded concrete anchor body is the main component of mooring equipment, and the provided anchoring force has a very important impact on the safety and reliability of engineering equipment. The Yellow River sand used in the test belongs to silty fine sand and its adsorption capacity is much bigger than normal sand under wet condition. In the study, a series of test schemes were designed to explore the influence of factors such as anchorage scale ratio, burial depth, shape, tension angle and water saturation on the anchorage force of concrete anchors in Yellow River sandy soil. Through model tests, the variation law of anchorage force coefficient with various factors was obtained.
