摘要
对徐州北部地区路用煤矸石的基本粒度特性及其颗粒破碎细化规律进行了试验研究,并综合分析了其对各种工程力学特性的影响,主要是压实、渗透、水稳、压缩、承载、变形与强度特性等。在此基础上,提出了适合于煤矸石的强度与变形本构模型。
The crushable properties of the colliery waste are studied in this paper. Based on the laboratory tests, the crushable effects on engineering characteristics of colliery wastes are then analyzed, including compaction, permeability, water stability, compressibility, bearing capability, strength and deformation properties. The constitutive model for colliery waste are finally presented.
