摘要
基于能量方法,利用势能驻值条件推导出了变截面高桥墩临界压力的计算公式,并比较了本文方法与ANSYS的计算结果.算例分析表明,该方法比ANSYS的计算过程更简便,而计算精度非常接近.
The calculation formulas for critical pressure calculation of high pier with variable section were derived by the condition of stationary value potential energy based on energy method, and comprised of results from this method with ANSYS. Analysis of examples indicates that the method not only simplified the calculation process but also got a calculation accuracy quite close to ANSYS.
