【摘要】 老堆积黄土类路基土作为我国西北地区交通线路路基的重要组成部分,其回弹模量是直接影响立即强度和路面设计与施工的重要指标,对于西北地区的交通路网建设与规划,优化其路面工程的工程设计与施工,保障交通路网建设的安全、高效、经济、合理,具有十分重要的意义.根据数学统计原理,通过对老堆积黄土类路基土回弹模量的大量试验结果的统计计算与变化规律的分析,得出了相应的结论.更多还原

【Abstract】 The old accumulation, that is the loessal earth, is the important component part of the roadbed earth for the transportation road in northwest region of our country. Its modulus of reboundelasticity has an direct effect on the instantaneous strength, the designing of road surface and the construction. Furthermore,it is an important parameter in the building and layout of transportation road net, the optimizing designing and constructing project,and the insuring security,effectiveness,economy and reasonableness in traffic road construction.According to the principle of mathematical statistics,and based on the statistical calculation of the testing data and the analysis of varying law for reboundelasticity modulus of old accumulating loessal roadbed earth,the corresponding conclusion is drawn.更多还原
