摘要
针对江西省高速公路多路段采用红砂岩填筑路基的工程实践,通过对已有工程的调查分析和大量室内外试验,提出红砂岩路基产生病害的主要原因,并深入探讨红砂岩的崩解性特点、规律及其用作路基填料时的性能和处理方法,研究结果可用于指导工程实践。
Based on the project practices on red sandstone filling roadbeds for multiple sections of expressways in Jiangxi Province,this paper proposes main causes of diseases existing in red sandstone roadbeds via investigation and analysis for existing projects and plenty of indoor and outdoor tests,and deeply discusses disintegrative features and rules of red sandstone and its performance when used as fill of roadbeds and treatment methods,the results of research can be applied for instructing project practices.
