为了分析钢锚梁索塔锚固区混凝土塔壁的水平受力性能，首先必须明确索力作用下混凝土塔壁和钢锚梁分别具体承担了多少水平力。为此，研究了各种构造形式下钢锚梁锚固体系的水平荷载传递途径，表明锚固区的水平荷载分配与结构的构造形式和施工过程有关。利用变形协调原理，推导了固定连接方式的锚固体系在斜拉索水平分力下钢锚梁与混凝土塔壁的荷载分配计算公式。研究了各种构造形式下钢锚梁锚固体系的水平荷载分配具体计算方法。通过有限元计算对简化计算公式进行验证，误差约为6．5％，表明简化公式具有较好的准确性。

In order to analyze the mechanical behavior of concrete tower wall in the steel anchor beam anchor-age zone of a bridge pylon,it is interested to understand the distribution proportion between the concrete tower wall and the steel anchor beam under cable force.This paper studied the load transfer pathways and distribu-tion relationship for the steel anchor beam anchorage system under various structural forms.It was found that that the load distribution was associated with structural forms and construction processes.By using the deform-ation compatibility principle,the load distribution formula of fixed connection anchorage system under the hori-zontal component of cable force was derived.The results calculated by using this simplified formula were com-pared with the finite element result,which indicates the validity of the formula with a error of about 6.5%.
