摘要
煤矸石作为一种新型的地基材料,具有特殊的物理力学特点。通过室内力学和土工实验,研究煤矸石的矿物成分、颗粒级配、压实特性及抗剪强度与压实度的关系。通过分析煤矸石的矿物组成、物理性质、化学成分等理化特性,以及作为回填建筑地基的可行性。结果表明:煤矸石的矿物成分与粘土很相似,易压实,将煤矸石回填作为建筑用地在技术上是可行的。
Gangue as the foundation of a new type of material, with special physical and mechanical characteristics.Mechanics and Geotechnical through the indoor experiment to study the mineral composition of coal, grain composition, Characteristics of compaction and shear strength and degree of compaction.By analyzing the gangue mineral composition, physical properties, chemical components, such as physical and chemical characteristics, as well as filling the feasibility of building foundations.The results show that：the coal and clay mineral composition is very similar, easy-to compaction, coal will be returned to the ground as construction sites is technically feasible.
