对海底管道建立微段和整体的力学模型，通过MATLAB编程求解顶部张紧器应提供给管道的张紧力。对比编程计算和Abaquas数值模拟结果，验证编程求解代替软件模拟计算的可行性和便捷性。探讨海域水深、管道入水角度、管重对张紧力的影响，结果表明，增加铺设水深和单位长度管重，所需张紧力增加；而增加铺设角度，所需张紧力相应减小。

The mechanical models of the segment and the whole submarine pipeline are established to calculate the tension at the top of tensioner by a Matlab software.Compare the numerical results with those obtained by simulations in Abaquas, show-ing that the simplified method is reasonable.The influence of sea depth, pipe-laying angle and pipe weight upon the tension is studied.As shown from the research results:the tension needed will become larger if the sea depth is larger or if unit pipe weight is heavier;if the laying angle is larger, the tension will be smaller.
