煤矸石浸水路堤不均匀沉降研究

首先通过对安徽淮南地区煤矸石进行室内材料试验,重点完成了抗剪强度、压缩模量等力学性能试验,结果表明其满足公路路堤材料的力学性能要求。采用ABAQUS有限元法分析不同影响因素对煤矸石浸水路堤路堤顶面处不均匀沉降的影响,对不同条件下路堤模的竖向顶面不均匀沉降并进行了参数敏感性分析。最后量化分析了各要素的影响程度并对其变化规律进行了研究。

Research on Deformation of Soaking Gangue Embankment

Material testing is firstly conducted for the coal gangue of a power plant in Taizhou city and it shows that the coal gangue can satisfy the basic requirement for mechanical performance requirements of highway embankment material. The influence of different factors on coal gangue embankment deformation is then analyzed by numerical simulation by using ABAQUS in uneven settlement of top surface, is calculated for the embankment model, and corresponding key factors are drawn through the research on the variation of the above deformation. Measures such as waterproof, drainage, grade elimination and compaction increase are finally suggested to improve the stability of the soaking gangue embankment.
