摘要
分析了水下生产系统在深海应用时所受环境载荷特点。通过对比,对目前应用较为广泛的几种水下生产设施的基础形式进行了研究。对打入桩、吸力桩和防沉板的适用环境条件、承载性能、安装便捷性和经济性进行了较为全面的分析,表明吸力桩的综合性能优于其他的基础形式,有广泛的应用前景。对吸力桩作为水下生产设施基础的受力情况进行了分析。根据吸力桩的结构和受载条件,说明了应用打入桩的承载能力计算方法来计算吸力桩的抗压能力和横向承载能力的合理性和局限性。
Outer loading condition of subsea systems in deep water is discussed. The mostly used types of foundations for subsea production equipments are compared. The relative merits of pipe pile, suction pile and mud mat is commented. The load applied on the suction pile in working con- ditions is analyzed. Based on the loading condition, the method used for axial and lateral bearing capacity calculation of pipe pile is suggested for the calculation of the bearing capacity of suction pile. The validity and limitation of the method is discussed.
