动荷载作用下桩在煤矸石中的振动传播规律研究

Pile Driving Induced Vibration Propagation in Coal Wastes

煤矸石是采煤过程和洗煤过程中排放的固体废物,是多种软岩成分的混合体,属于"软质粗粒土"。要将煤矸石变废为宝,拓宽其用途渠道,必须对其在不同用途下的特性规律进行科学的数字化分析。采用ANSYS软件建立结构有限元模型,分析研究动荷载作用下桩在煤矸石中的振动传播规律,为更好地利用煤矸石提供参考。

The coal waste is a solid waste material consisting of a mixture of various soft rock components during the coal min ing and processing. It can be classified as “soft coarse grain soil.” If the coal waste left untreated, it might take a large quantity of treasures land and it will cause the contamination if the sulfate from the coal waste is leached out. To widen the areas that the coal waste can be reused, the quantified analysis of the properties of the coal waste under different conditions is very impor rant. This paper presents a finite element analysis model using ANSYS to examine the pile driving induced vibration propaga- tion in the coal waste.
