摘要
以现场试验数据为基础,合理考虑"拱效应"原理,试验结果表明:高填方涵洞顶部土压力随填土高度增大呈非线性增大规律,运用回归分析法提出了涵洞顶部竖向土压力计算公式,使高填方涵洞结构设计更为经济合理。
Based on the field test data, considering reasonably"arching effect"principle, this paper studied the arching effect and calculation analysis of high embankment culvert top soil. The experimental results showed that high embankment culvert top soil pressure was nonlinear increasing law with the increase of soil-filled height.Using the regression analysis method, it also put forward the calculation formula of culvert top vertical soil pressure, which made the high embankment culvert structure design more economic and reasonable.
