摘要
本文通过力学分析和有限元分析处理理想的管道模型,研究了城市环境施工中地质灾害对管道的侵害情况,重点关注滑坡和坍塌等地质灾害。具体而言,本文讨论了管道在地质灾害中的受力情况,包括拉力和压力情况下的计算方法,提出了分析模型如何根据管线材料等信息来预测裸露长度的极限,并对地质灾害引起的管道破坏风险进行预测和评估。综合而言,本文通过理论分析和有限元分析,研究了城市环境施工中地质灾害对地下管道的影响,提出了科学的预测方式和防控措施,为城市基础设施中地下管道的安全管理提供了重要支撑。
In this paper,the ideal pipeline model was processed through mechanical analysis and finite element analysis,and the damage of geological disasters to pipelines in urban environment construction was studied,focusing on geological disasters such as landslides and collapses.Specifically,this paper discussed the stress of pipelines in geological disasters,including the calculation methods under tensile force and pressure conditions,proposed how the analysis model could predict the limit of bare length based on pipeline materials and other information,and predicted and evaluated the risk of pipeline damage caused by geological disasters.In summary,through theoretical analysis and finite element analysis,this paper studied the impact of geological disasters on underground pipelines in urban environmental construction,and proposed scientific prediction methods and prevention and control measures,which provided important support for the safety management of underground pipelines in urban infrastructure.
