浅谈某尾矿库排水管承载能力复核计算

Discussion on Checking Calculation of Bearing Capacity of Drainage Pipe in a Tailings Pond

排水管是尾矿库排洪系统的重要输水构筑物,其结构形式多为钢筋混凝土结构。近些年,由于排水管结构强度的降低导致排洪系统失效是引起尾矿库安全事故的主要原因之一。本文介绍了某尾矿库闭库后,对库内已建排水管结构承载能力进行复核。通过对排水管承受的荷载计算和有限元分析,已建排水管承载力满足闭库后使用要求。

Drainage pipes are the vital water conveyance structure within the tailings pond flood discharge system,typically taking the form of reinforced concrete structures.In recent years,the reduced structural strength of drainage pipes leading to flood discharge system failure has been one of the main causes of safety incidents in tailings ponds.This paper presents a reevaluation of the load-bearing capacity of the established drainage pipe structures within a tailings pond after its closure.Through load calculations and finite element analysis performed on the drainage pipes,it was found that the existing structures have a load-bearing capacity that meets the requirements for use after the pond closure.
