摘　　要：主索张力是浮桥横张纲锚定计算的主要内容 ,传统计算理论考虑浮桥横向是绝对刚性的。在实际情况中 ,浮桥在水流阻力的横向作用下产生弹性变形 ,导致横张纲锚定系统内的受力重新分配。建立基于弹性变形理论分析横张纲锚定系统的内力变化规律的公式 ,并通过具体算例分析多种工况条件 ,为解决此类问题提供了有益的手段。Analysis of the main cable's tension is the new conception of calculation of anchorage by stream cable of float bridge. Traditional theory considers the float bridge segment horizontal elasticity bent for absolutely rigid. But in the actual condition, elasticity transfiguration will occur under acting of horizontal stream resistance. It resets the inner force of the system. The formulas of the inner force variation regulation of the system are established. And the concrete examples of several conditions are analyzed so that the appropriate methods for solving the similar problem are acquired.
