某高速公路北留至阳城段拓宽改造工程方案研究

Schematic Studies on Broaden Reconstruction Engineering of Certain Highway Beiliu-Yangcheng Section

针对某高速公路标准低、运行安全性差、服务能力和水平已无法满足交通量需求这些问题,从平纵指标、拆迁占地、行车安全、环境影响等方面提出改扩建方案,经分析比较,提出最优改扩建方案。

In this paper, dynamic resilience modulus of graded crushed rock under different compaction and moisture condition were tested, and then the influence of compaction, moisture content and stress conditions on material dynamic modulus of resilience was analyzed. The results showed that the weak of modulus caused by low degree of compaction could be compensated with larger stress. Compared with the moisture content, the compaction effect on the modulus was weak. Overall dynamic resilient modulus grow with deviatoric stress, but with the growth of the confining pressure, the growth rate would get smaller.
