摘要
简要介绍了圆管涵破裂的原因,论述了根据公路规范、铁路规范计算涵洞顶填土压力的方法及其缺陷,提出了一种新的涵洞顶填土压力计算方法。计算结果表明,该方法克服了上述两种规范中计算方法的不足。
The causes of culvert damage is introduced . Defect of calculation of earth pressure on the top of culverts based on highway standard or railway standard is elucidated. A novel calculation method is proposed to calculate the earth pressure on the top of culverts. The calculation results show that the defect of calculation based on highway standard or railway standard is avoided by using this novel method.
