LOAD STRESS ANALYSIS OF PRESTRESSED CONCRETE PAVEMENT
预应力混凝土路面的荷载应力分析方法

The method of the finite-infinite element is suggested to calculate the stress and deformation of prestressed concrete pavement according to its structural characteristics. The iteration model of friction force at slab bottom is adopted,which is coincident much more with the working condition of PCP than the others before. Multi-direction mapped infinite element is adopted to reflect that zero displacement in infinite. The calculating results show that the analytical model is correct. The investigation is valuable for the design and construction of prestressed concrete pavement.
