摘要
根据预应力混凝土结构的材料非线性与几何非线性性质，编写了预应力梁式公路桥的有限元微机计算程序，模拟实桥在运营条件下和濒临破坏时的极限承载力。用此程序对柳州市第二大桥结构进行了分析计算，并与实测结果做了对比，吻合较好。
According to the prestressed concrete structure in the property of non-linear of material and geometry, the finite element computer program of prestressed beam highway bridge is computed, and the limited load under the condition of being close to destroying as well as being in motion is simulated. Thereby, the Construction of the Second Bridge in Liu Zhou City is analyscd with that program and the computational results against the measured results arc checked, which are coincidental very well.
