摘要
黄土类土路基作为我国西北地区交通道路路基工程的重要形式,路基土的回弹模量直接受到其地质成因的影响与控制.通过对不同地质成因的黄土类路基土回弹模量大量试验结果的统计计算与分析,总结出了它们之间的变化规律,分别给出了p-l和p-Ee关系曲线,对于西北地区交通路网建设具有十分重要的现实意义和实用价值.
The roadbed of loessal earth is an important form in northwest region of our country,and it is affected from its cause of formation. On the basis of the statistical calculating and analyzing of the large numbers of testing data for the roadbed earth of the different cause of formation,the difference of these roadbed earth on the modulus of rebound-elasticity is summarized,and the graphs of p-l and p-E_e is obtained.This is important to build transportation road net in our northwest region.
