目前对连续刚构桥梁认识的局限性,很多大跨径连续刚构桥均出现不同程度的病害。在现有认识的基础上,如何克服和尽量减少病害的产生,是目前在设计过程急需解决的问题。
At present, the limitations of continuous rigid frame bridges are recognized. Many long-span continuous rigid frame bridges suffer from varying degrees of disease. On the basis of the current understanding, how to overcome and minimize the occurrence of diseases is an urgent problem to be solved in the design process.
