A Simplified Mechanical Model and Analysis for the Settlement Deformation of Buried Pipelines Caused by Open-Cut Excavation

This study aims to reveal the deformation characteristics of buried pipelines and effects various parameters on settlement displacement using analytical analysis method. A simplified mechanical model for is proposed with theory Winkler model, sensitivity impacts are performed by comparing them those given other cases. The rationality approach verified a comparison previous cases, it also turned out that present method better than two methods in literature its overall tendency error precision. parameter results this indicate maximum only increases linearly increase ground displacement. Other such as subgrade modulus calculated length certain threshold; will remain stable. However, diameter elastic have small effect pipelines, so they not sensitive factor these can be ignored. In addition, an engineering example pipeline deep foundation pit from open-cut excavation researched verify practicality
