为了研究沿涵洞纵向不同位置的涵顶竖向土压力的分布规律,基于分布角法推导了土压力计算法,分析了土压力沿涵洞纵向的分布规律,探讨了拱效应,结果表明涵顶拱效应使规范的“土柱法”计算值偏大,结构过于安全而不经济。
為瞭研究沿涵洞縱嚮不同位置的涵頂豎嚮土壓力的分佈規律,基于分佈角法推導瞭土壓力計算法,分析瞭土壓力沿涵洞縱嚮的分佈規律,探討瞭拱效應,結果錶明涵頂拱效應使規範的“土柱法”計算值偏大,結構過于安全而不經濟。

To investigate the pattern of vertical earth pressure on longitudinal culvert,based on distributing angle method,the calculation method of vertical earth pressure was deduced. The law of earth pressure was analyzed and the arching effect was discussed. The calculated results by“soil column method”in code was large. Structure is not cost-efficient because design is too safe.
