水温耦合作用下风化砂岩崩解和质量流失研究

随着公路建设向山岭重丘区的转移,如何就地取材,利用风化岩进行路基填筑,以弥补山区路基填料的不足,已成为亟待解决的问题。为确保风化砂岩填筑路基长期使用性能,提出水温耦合作用下风化砂岩崩解和质量流失的试验测定方法,并将材料的干湿循环崩解率和质量流失率与风化程度进行了相关性分析。

Study on Disintegration and Mass Loss of Weathered Sandstone Under Moisture-temperature Coupled Action

With the Wansfer of highway construction to the mountain re-Hill District, It＇s an urgent solution to use the local wide range of weathered rock for embankment to make up for lack of mountain quality stone filling. In order to ensure the long termperformance of weathered sandstone, the paper gives methods of the disintegration test and the mass loss test under moisture-temperature coupled action, and makes correlation analysis o fdegree of weathering and sandstone disintegration rate, mass lo ss rate under dry-wet cycle action.
