目前,高速铁路以较快速度发展。为满足日益严格的高速铁路路基的变形要求,现急需找到对现有高速铁路路基适用的路基改良方案。本文通过理论与实践相结合的方法分析,对比石灰改良黄土前后的击实特性、压缩特性、强度特性以及其他工程力学特性的主要因素,为铁路路基的改良提供部分参考。
At present, the high-speed railway is developing at a faster speed. In order to meet the increasingly strict requirements of deformation of high-speed railway subgrade, it is urgent to find a suitable subgrade improvement program for the existing high-speed railway subgrade. Through the analysis of the theory and practice, this paper compares the compaction, compression and strength characteristics of limestone before and after loess improvement with other engineering mechanics characteristics, and provides some references for the improvement of railway embankment.
