摘要
结合辽宁某高速公路桥梁受火后的承载能力试验,分析受火灾后预应力空心板的性能变化情况,总结初步确定火灾损伤后公路预应力空心板梁残余承载能力的一种方法。
In the light of testing bearing capacity of a certain bridge on freeway,which underwent fire,in Liaoning Province,the paper analyzes the change of performance of prestressed voided slab which underwent fire, and sums up a method which is able to determine preliminarily the remaining bearing capacity of above voided slab.
