Abstract

Abstract:

In this paper， the reasonable numerical model of CRCP with double-layer reinforcement under the action of temperature shrinkage is explored and verified. The error analysis and reliability analysis of the finite element calculation results and rectangular coordinate solutions are carried out to determine the reasonable analysis model. The L50 table was used to design the orthogonal test scheme of reinforcement factors， and the sensitivity analysis of design parameters affecting the reinforcement ratio of CRCP with double-layer reinforcement was carried out， and the influence law was studied. Through range analysis， variance analysis and significance evaluation， the sensitivity of each design parameter and the significance of the influence level are judged， the coefficient of linear expansion， temperature drop， reinforcement ratio， bond stiffness coefficient， and elastic modulus of steel rebars have significant effects on the mechanical response of CRCP with double layer reinforcement， and should be used as the main design indexes. It is suggested that the reinforcement ratio ρ according to ρ∈［0.60%，0.80%］、 ρ∈［0.80%，1.00%］、 ρ∈ ［1.00%，1.20%］ three value ranges for trial calculation； Take 1 / 3 of the thickness of CRC slab as the value point of longitudinal reinforcement.

Key words: road engineering, double layer reinforced CRCP, longitudinal reinforcement ratio, design parameters, significance ranking
