Chemical Mechanism Analysis on Lime Improvement for High Speed Railway Loess Filling
-
摘要: 通过分析某高速铁路客运专线路基黄土填料土质改良试验成果，对采用石灰改良黄土的化学机理进行了分析探讨，指出经过改良的黄土能够作为高速铁路路基的填料，土质改良试验的主要任务是确定经济合理的配合比及最佳含水量。Abstract: Based on the.soil improvement testing results of loess filling in one Passenger Dedicated Line Project, the chemical mechanism for lime improved soil is investigated. It is pointed out that the improved loess is qualified as filling material for subgrade of the high speed railway project, and the major task of the rail improvement tests is to determine the economic rational mix ratio as well as the optimum water content.
