Load Transfer Capacity Analysis of Prefabricated Steel Fiber Concrete Pavement Slab
摘要
The joint of prefabricated concrete pavement slab is an important structural part of the prefabricated pavement slab. The joint damage will reduce the pavement function and accelerate the plate damage. The joint treatment technology is also a problem that puzzles engineering researchers. How to ensure the mechanical properties, load transfer rate and life of the assembled road joint has become the main research direction of the assembled road. This paper takes the indoor test as the research method, analyzes the bending and strain of the indoor test groove and lap joint. It is found that the bending value of the groove joint is large, and the tensile strain is the main one, which is easy to be damaged by tension. Through the comparative test, it is suggested that the joint form of the assembled road slab should adopt the lap type.
