千枚岩是一种不良路基填料,由于十天高速沿线气候、地形、地质条件复杂,弃借方都较困难,且千枚岩分布广泛,必须利用千枚岩做为原料,因此填筑路床时必须对千枚岩进行改良。目前我们常用改良方式主要有2种,一种是石灰岩改良,一种是水泥改良。本文主要介绍水泥改良的方式及处理,为千枚岩的利用提供参考。
Phyllite is a kind of unfavorable subgrade filler. Due to the complicated climate, topography and geological conditions along the 10-day high speed, the delinquent debts are more difficult and the phyllite is widely distributed. Therefore, phyllite must be used as the raw material. Therefore, Phyllite must be improved. At present, there are mainly two kinds of improvement methods that we commonly use, one is limestone improvement and the other is cement improvement. This paper mainly introduces the ways and treatments of cement improvement, and provides reference for the utilization of phyllite.
