摘要

通过室内试验，研究了高云母含量的云母片（麻）岩风化料的压实性能、水稳定性、CBR等工程特性。结果表明，由于云母片表面极光滑

且具有高弹性，大量云母片的存在使得风化料颗粒间嵌挤能力差，抗剪能力低，在击实过程中易出现表层起皮、松散和回弹现象；其水稳定性差，强度偏低，CBR值达不到高速公路上路床填料的强度标准；增加击实功，不能明显改善材料的压实性能；利用该类材料填筑路基，宜采用静压施工，避免振动碾压。对该类材料采用黏土、风化砂、水泥改性后，可明显改善材料的压实性能，提高材料的强度。从工程经济的角度提出了合理的改性材料外掺剂量。

Abstract

Through the laboratory experiment

the compaction performance

water stability

CBR of the weathered mica gneiss have been studied. Because of the high elasticity and extremely smooth surface

mica sheets cause the low ability of inlay and anti-cuts. It is easy for the surface layer of the subgrade to peel

loose and to rebound. Then the water stability is bad

the intensity is somewhat low

and the CBR value cannot achieve the intensity standard of the roadbed in the highway. Increasing the work of tamping

the compaction performance of the material cannot be improved obviously. For the construction of the bed

the static pressure is suitable avoiding dynamic pressure. The compaction performance of the material may be obviously improved; and the intensity of the material may be enhanced after improving it with the clay

the weathered soil or the cement. The reasonable admixture dosage of the modified material can be proposed from the engineering economic aspects.
