摘要

高精度变形监测对于研究滑坡与管道相互作用问题至关重要,而光纤神经系统(FONS)在这方面具有巨大潜力。本文介绍了利用光纤神经系统解释滑坡与管道相互作用的理论框架,并提出了一种基于分布式应变测量计算管道-土壤界面特征参数的新方法。通过全尺寸模型试验验证了该方法的可行性,并在位于中国三峡库区的新蒲滑坡中演示了该方法在研究管道行为中的应用。实地监测结果表明,短时高强度降雨事件会立即引发滑坡加速运动,导致管道伸长和弯曲。通过对地下管道的应变测量,可以确定滑坡的局部滑动界面。此外,还分析了水库水位(RWL)波动、降雨事件、滑坡变形和管道结构响应之间的关系。研究结果表明,滑坡前段和中段的变形与降雨量和水库水位下降的综合影响有很高的相关性。

Performance evaluation of underground pipelines subjected to landslide thrust with fiber optic strain sensing nerves

High-accuracy deformation monitoring is crucial for investigating landslide–pipeline interaction problems, in which the fiber optic nerve system (FONS) holds enormous potential. This paper presents a theoretical framework for interpreting landslide–pipeline interactions using the FONS and proposes a novel method for calculating characteristic parameters of pipe–soil interfaces based on distributed strain measurements. The feasibility of this method is validated through a full-scale model test, and its application for studying pipeline behaviors is demonstrated in the Xinpu landslide, situated in the Three Gorges Reservoir region, China. The field monitoring results reveal that short-duration, high-intensity rainfall events triggered immediate acceleration of landslide movements, leading to pipeline elongation and flexure. Strain measurements of the underground pipeline allow for the identification of the local slipping interface of the landslide. Furthermore, the relationships between reservoir water level (RWL) fluctuations, rainfall events, landslide deformation, and the structural response of the pipe are analyzed. The findings suggest that the deformation of the landslide in the leading and middle parts exhibits high correlations with the combined effect of rainfall and RWL drawdown.

期刊介绍: Acta Geotechnica is an international journal devoted to the publication and dissemination of basic and applied research in geoengineering – an interdisciplinary field dealing with geomaterials such as soils and rocks. Coverage emphasizes the interplay between geomechanical models and their engineering applications. The journal presents original research papers on fundamental concepts in geomechanics and their novel applications in geoengineering based on experimental, analytical and/or numerical approaches. The main purpose of the journal is to foster understanding of the fundamental mechanisms behind the phenomena and processes in geomaterials, from kilometer-scale problems as they occur in geoscience, and down to the nano-scale, with their potential impact on geoengineering. The journal strives to report and archive progress in the field in a timely manner, presenting research papers, review articles, short notes and letters to the editors.
