桥梁支座反力的确定决定了支座型号的选择,支座反力对桥梁的施工及运营状态影响较大,支座反力的合理性是评价一座桥梁结构受力是否合理的重要标志,反力大小也是评价一座桥梁是否安全的重要因素,选择合适的桥梁支座能将经济和社会效益发挥到最大,也能确保行人车辆的安全。该文以南宁市五象大桥为工程背景,对其合理支座反力的确定进行了探讨。
The determination of reaction force of bridge support determines the choice of bearing model. Bearing reaction force has a great influence on the construction and operation status of bridge. The rationality of bearing reaction force is an important symbol to evaluate whether the force of a bridge structure is reasonable. The reaction force is also an important factor to evaluate the safety of a bridge. Choosing the right bridge bearing can maximize the economic and social benefits and ensure the safety of pedestrian vehicles. This paper takes Nanning Wuxiang Bridge as the engineering background and discusses the determination of its reasonable bearing reaction force.
