基坑开挖引起管线位移影响规律研究
摘要:近年来随着基坑工程的发展,基坑开挖引起周围环境变化乃至周围建筑物、地埋管线变形或断裂破坏的事故屡见不鲜。所以应加强对基坑工程的研究,减少此类事故的发生。利用数值模拟的方法,对基坑开挖过程中基坑周围地埋管线受基坑开挖影响而导致管线位移变化规律进行研究。归纳总结基坑开挖对周围地埋管线位移的影响规律,并对地埋管线在基坑开挖过程的支护提出建议。
Abstract:With the development of the foundation pit engineering in recent years,excavation cause changes in the surrounding environment and even the surrounding buildings, underground pipeline deformation or fracture damage accidents are common. So we should strengthen the research of foundation pit engineering, reduce the occurrence of such accidents. In this paper, by using the method of numerical simulation, during the process of excavation of foundation pit surrounding buried pipelines affected by excavation caused variation of pipeline displacement. This paper summarizes the influence of excavation displacement around buried pipeline,and put forwards some suggestions on the buried pipelines in the excavation process of foundation pit supporting.
