通过对钢桥吊装时的内力分析，对钢桥受力部位进行局部加强，以改善各杆件内应力满足强度要求，研究采用托架替代吊架的安装方案优化。经过工程实际检验证明，该方案有利于减少临时措施的投入和对大型船机设备的性能要求，降低施工成本。
通過對鋼橋弔裝時的內力分析，對鋼橋受力部位進行跼部加彊，以改善各桿件內應力滿足彊度要求，研究採用託架替代弔架的安裝方案優化。經過工程實際檢驗證明，該方案有利于減少臨時措施的投入和對大型船機設備的性能要求，降低施工成本。

Through the stress analysis on the hoisting of steel bridge, we made local reinforcement for the stress parts of steel bridge to improve the rod stress in order to meet the strength requirements, studied the optimal installation scheme by bracket replacing hanger. The engineering practice proves that it is advantageous to reduce the temporary measure input and require-ments of the large ship equipment performance, and reduce the construction cost.
