无粘结预应力混凝土箱形梁三维应力计算方法

Calculation method of three-dimension stress for no-bonding inherent stress concrete box-beam

利用有限元分析软件ANSYS,建立了无粘结预应力混凝土箱形梁桥单梁的三维有限元模型,并与材料力学计算方法及工程实测数值进行了比较,结果表明此有限元模型是合理的、实用的。

It builds three-dimension finite element model of no-bonding inherent stress concrete box-beam applying for finite dement analytic software ANSYS, and compares it with coloration of material mechanics and actual measurement value, the result indicates it is reasonable and serviceable.
