膨胀土CBR浸水膨胀量的探讨

本文通过总结国内膨胀土膨胀量变化,明确了浸水CBR膨胀量标准,以便于更好地控制路基填筑材料的质量。同时分析了自由膨胀量和CBR浸水膨胀量的关系,提出了CBR浸水膨胀量的要求。

This paper attempts to determine the standard of swelling amount of soaking CBR through the brief summary of the change of swelling amount of swelling soil so as to better control the quality of subgrade filling material. Meanwhile it makes an analysis of the relationship between free swelling amount and CBR soaking swelling amount, and puts forward the requirements of the latter.
