摘要
采用 8结点等参元的有限元方法 ,对海上吸力锚负压沉贯过程中锚体周围土体的渗流场进行了数值计算与分析 ,并给出了渗流场相关要素的计算方法 ,如水头、等势线、渗流力、渗流速度和渗流量等。通过对实例的分析 ,计算结果和结论令人满意 。
This paper adopts the method of eight-point isoparametric finite element to carry out the calculation and analysis to the of suction penetration field of a suction anchor. It offers the calculation method to certain elements of suction penetration seepage field, such as water head, hydrostatic strength, seepage force, fluxing velocity distribution and the amount of seepage. Through analysis to the result data of practical examples, some satisfactory regulation could be obtained to support the design of suction anchor.
