在建立同时考虑墩顶支座和结构体系约束的等效刚度公式基础上，求解墩顶在弹性约束下的压杆计算长度系数精确方法。进而分别研究墩高和柱径对计算长度系数的影响，并基于不同的压杆计算长度系数选取方法，对高墩截面配筋的需求进行敏感性分析比较。

Considering the pier top bearing and the constraint of the structural system ,the equivalent stiffness for-mula has been established ,and the accurate calculated length coefficient method of pressure bar in the pier top under e-lastic restraint is also derived.then the Influence of pier height and column diameter is respectively discussed.Based on the different calculation length coefficient of pressure bar ,the sensitivity of the high pier reinforcement demand is ana-lyzed.
