摘要
根据相似性原理对高填方路堤涵洞进行室内模型试验研究,分析高路堤涵洞的垂直土压力分布规律和位移变化规律,试验结果表明:在上部碎散体填土达到一定高度且在涵中填土沉降量大于涵侧填土沉降量的情况下,土体中将产生成拱效应。
Indoor model test research on high-filling embankment culvert is conducted according to similarity principle to analyze the vertical soil stress distribution regularities and displacement change rules.The test results show that arch effect will exist in soil when the upper broken ore fills to some height and filling soil settlement in culvert is bigger than that of the lateral of culvert.
