尾矿库排水管纵向强度浅析

Analysis of longitudinal strength of drainage pipeline in tailing dam

采用文克尔地基模型对尾矿库排水管纵向强度进行了分析，结果是：如果作用在排水管上的荷载沿管轴线是线性分布，无论其大小，只要排水管是有限长的，在其纵向上将不产生或产生不太大的内力。因此，建在土基上的尾矿库排水管可根据规范规定，适当延长管长。

The longitudinal strength of drainage pipeline in tai ling dam was analysed using the Winkels foundation model,and the following results were obtained:so long as the drainage pipeline is of limited length,there will no or not too large external force occur along its longitudinal direction,if the load (no matter how large it is),applied along the axis of pipeline,is distributed linearly.Therefore,the drainage pipeline laid on soil foundation could be extended properly according to the related regulations,and it is unnecessary to shorten the pipeline for increasing the longitudinal fracture strength.
