Deep-sea pipelines play a pivotal role in seabed mineral resource development, global energy and resource supply provision, network communication, and environmental protection. However, the placement of these pipelines on the seabed surface exposes them to potential risks arising from the complex deep-sea hydrodynamic and geological environment, particularly submarine slides. Historical incidents have highlighted the substantial damage to pipelines due to slides. Specifically, deep-sea fluidized slides (in a debris/mud flow or turbidity current physical state), characterized by high speed, pose a significant threat. Accurately assessing the impact forces exerted on pipelines by fluidized submarine slides is crucial for ensuring pipeline safety. This study aimed to provide a comprehensive overview of recent advancements in understanding pipeline impact forces caused by fluidized deep-sea slides, thereby identifying key factors and corresponding mechanisms that influence pipeline impact forces. These factors include the velocity, density, and shear behavior of deep-sea fluidized slides, as well as the geometry, stiffness, self-weight, and mechanical model of pipelines. Additionally, the interface contact conditions and spatial relations were examined within the context of deep-sea slides and their interactions with pipelines. Building upon a thorough review of these achievements, future directions were proposed for assessing and characterizing the key factors affecting slide impact loading on pipelines. A comprehensive understanding of these results is essential for the sustainable development of deep-sea pipeline projects associated with seabed resource development and the implementation of disaster prevention measures.

预测深海流态化滑坡对管道的冲击力：关键因素的全面回顾

深海管道在海底矿产资源开发、全球能源资源供给、网络通信、环境保护等方面发挥着关键作用。然而，这些管道布置在海底表面，使其面临复杂的深海水动力和地质环境，特别是海底滑坡带来的潜在风险。历史事件凸显了滑坡对管道造成的严重损害。具体而言，以高速为特征的深海流化滑坡（处于碎片/泥浆流或浑浊流物理状态）构成了重大威胁。准确评估流态化海底滑坡对管道的冲击力对于确保管道安全至关重要。本研究旨在全面概述流态化深海滑坡引起的管道冲击力的最新进展，从而确定影响管道冲击力的关键因素和相应机制。这些因素包括深海流化滑道的速度、密度和剪切行为，以及管道的几何形状、刚度、自重和机械模型。此外，还在深海滑坡及其与管道相互作用的背景下检查了界面接触条件和空间关系。在对这些成就进行彻底审查的基础上，提出了评估和表征影响管道滑动冲击载荷的关键因素的未来方向。全面了解这些结果对于与海底资源开发相关的深海管道项目的可持续发展和防灾措施的实施至关重要。
