【摘要】 软质岩风化物多属于C、D组填料,不宜直接用于客运专线路基填筑,使用时应进行改良。无侧限抗压强度是反映软岩改良土物理力学特性及水稳性的一个重要指标。采用灰关联熵方法,通过对不同掺灰量、不同龄期、不同压实度下改良土的无侧限抗压强度进行研究,分析无侧限抗压强度的主要影响因素,为软岩改良土的设计与施工提供一定的参考。更多还原

【Abstract】 Soft rock,which is not suitable to be used directly for roadbed filling of passenger express railway,almost belongs to the group C and D filling,and it should be improved during using.The unconfined compression strength is the important target,which relate to the physical properties and water stabi-lities of modified soil of soft rock.The unconfined compression strength of modified soil in different proportions of cement,different curing ages and different degree of compaction is studied by the grey relation entropy method.The mail influence factors of unconfined compression strength are analyzed and some reference for the design and construction of modified soil of soft rock are provided.更多还原
