斜拉桥设计方案探析

以印尼Mahkota斜拉桥的设计为背景，在原桥原有构造基础上进行了部分调整，用桥梁博士3．03中的调索模块计算确定最佳初始索力，并用该软件模拟斜拉桥施工过程及各种正常使用工况，进行全桥内力分析。根据印尼规范要求验算施工和使用阶段主梁、主塔、拉索的安全性，借此简要介绍斜拉桥的构造设计要点及用桥梁博士进行斜拉桥静力方面计算的要点，总结整个设计中部分优势，对中等跨度的斜拉桥的设计具有一定的借鉴性。

Analysis on Cable-Stayed Bridge Design

Taking the design of Mahkota cable-stayed bridge in Indonesia as an example, this paper made some adjustments in the original structure design of the bridge. Then the paper calculates and determines the best initial cable forces by Dr. Bridge 3.03 with the cable adjustment module, simulates the cable-stayed bridge con- struction process and the normal work of the software, and analyzes the whole bridge internal force. According to the safety checking requirement about the main beam, tower and cable in Indonesian specification, this paper in- troduces the points of structure design and the static calculation points of cable-stayed bridge with bridge doctor, summarizes some advantages in the design. It hopes to provide reference to certain design of cable-stayed bridge of middle span.
