摘要
主要介绍独塔斜拉桥有关参数的研究，其中主要是关于主跨主梁边支座附近无索区合理长度的研究。不相同的无索区长度设置，必然对斜拉桥的主梁内力、挠度和塔顶侧移等产生不同的影响，结合考虑到施工等影响因素，经比较本文给出合理的无索区长度建议值。
In most modem cable-stayed bridges, the bridge deck is supported by closely spaced cables. In single tower cable -stayed bridges in particular, the lengths of ' unsupported' deck adjacent to the end supports are the important para -meters that affect the internal forces and deflections of the deck and the tower. This paper describes the studies of the above-mentioned parameters and shows the influences on whole structure for different unsupported lengths of deck adjacent to end supports taking into account the practical problems of construction.
