浅埋PVC管道穿越挖填方场地时受力状态研究
The study of positive buried pipeline's strained condition crossing the transition zone of high embankment
摘要
Abstract
This paper took the PVC drainage pipeline in Yan'an District of loess gully high embankment engineering as the test's prototype. By making a 1:2 physical model test, the combination of filling and excavation site of shallow buried PVC pipes in the post construction settlement was simulated during the stress and the deformation process. The deformation of pipeline, pipe soil contact pressure and strain data were obtained. Studies show that when the deep ground subsidence quantity is greater than 6 mm, pipe in various parts of the stress state of differentiation and pipeline interface for the adverse effects at this stage starts to appear. The pipeline interface is not recommended layout in cut fill transition zone and the middle of high fill.关键词
