Unsaturated soil-structure interaction with emphasis on buried pipelines

地下管道网络是运输和分配水、石油和天然气资源的最常见方式，管道故障可能会产生重大的社会经济和环境影响。我们的目标是开发一个框架，用于描述土壤管道相互作用的机制，旨在降低受地质灾害影响的管道的故障风险。该项目旨在使用新的定制设备在实验室中模拟管道的响应。实验结果有望为开发一个理论模型，以量化土壤水分对管道完整性的影响，并提出设计公式提供见解。为处理岩土工程中各种非饱和土-结构相互作用问题提供了一个通用框架。

Buried pipeline networks is the most common mode of transporting and distributing water, oil and gas resources and pipeline failures may have a major socioeconomic and environmental impact. The goal is to develop a framework for describing the mechanisms underlying soil-pipe interaction, aiming to reduce the failure risk of pipes affected by geohazards. The project aims to model the response of pipelines in the laboratory, using a new custom-built apparatus. Experimental results are expected to provide insight for developing a theoretical model to quantify the effect of soil moisture on pipe integrity, and propose design formulas. A general framework is intended to be developed for handling various unsaturated soil-structure interaction problems in geotechnical engineering.
