从避免吊杆断裂破坏和增强整个结构体系对单根吊杆破坏耐受能力方面,探讨了吊杆拱桥的安全性预防设计,供同类桥梁设计借鉴和参考。为避免吊杆突然破坏,设计时应考虑吊杆及其锚固构造的可检、可修、可换,从而增强吊杆寿命和结构安全。 In order to avoid the rupture of the boom and enhance the ability of the whole structural system to withstand the damage of a single boom, the safety precautionary design of the boom arched bridge was discussed for reference and reference of the similar bridge design. In order to avoid the sudden destruction of the boom, the design of the boom and its anchoring structure should be considered as checkable, repairable and exchangeable so as to enhance the life of the boom and the structural safety.
