山区高等级公路加筋高路堤陡边坡研究

介绍加筋高路堤陡边坡的室内外研究成果：用离心模型研究加筋陡边坡的变形性态和经济合理的布筋方案；修筑高21．0m,坡比1：0．75的加筋高路堤陡边坡，对加筋陡边坡的技术可靠性和经济性作了现场验证和评估。结果表明，加筋高路堤陡边坡能养活占地拆迁，增加高填方边坡的稳定，技术性能安全可靠，经济效益显著，在山区公路路基边坡稳定中具有良好的推广应用前景。

An lnvestigation of Reinforced High Fills Steep Slope

The investigation　results of a reinforced high embankment steep slope are presented in this paper. Four centrifugal models are tested to determine the lateral displacement characteristic and reasonable reinforcement distribution of reinforced steep soil slope. A demonstration reinforced steep slope is built for an expressway. The model test results indicate that the soil slope and the reinforced slope have similar lateral displacement characteristic, and increasing the numbers of reinforcement layer at the middle of slope is a reasonable way of reinforcement distribution. The demonstration project shows that the reinforced steep slope is not only reliable in technical but also cost effetive than the soil slope.
