Load Stress Analysis of Unbonded Prestressed Concrete Pavement
A 20-node isoparametric element is implemented for the stress analysis of prestressed concrete pavement (PCP). The model of friction force at the slab bottom is presented and the friction force is found to correspond much more to the working condition of PCP than that other models have suggested. The longitudinal prestress equivalent model is established and a stress calculation method of higher accuracy is introduced. Numerical examples and experimental data both verify the effectiveness of the analytical model and program. Load stress of the unbonded PCP is researched in detail using the data from the first domestic experiment road. The test results and comparison analysis can provide important reference for prospective design and construction of PCP.
