连续悬索桥基础沉陷时对索塔的附加内力

Addional Forces to Tower of Three-Span Continuous Suspension Bridge When Foundation Sinking

提出了三跨连续悬索桥当基础沉陷时导致索塔附加内力的模拟计算图式 。

This paper provides the simulated calculation scheme for additional forces to the tower of three span continuouse suspension bridge when the foundation sinks, and gives the simple formulas which are applicable to calculate with hand. Therefore it has practical signficance for designer.
