A field guide to the engineering geology of the French Alps, Grenoble

It is now well established in the field of engineering geology that a comprehensive ground model is critical to the success of any engineered project. This ground model must contain elements of the site geology, geomorphology and geotechnics and demonstrate the potential interactions between these elements to be of value to the engineer or geologist working on a given project. The area around Grenoble in the French Alps offers an ideal field location to exemplify and demonstrate these concepts. Here there are a number of large engineering structures that highlight the importance of sound engineering geological investigation and the establishment of detailed ground models to understand problematic ground behaviour and performance. The area demonstrates the key issues of geotechnical hazard, vulnerability and associated risks, as well as the significance of understanding both the solid and superficial ground conditions. This field guide provides details on and discusses a variety of key localities where these issues can be fully demonstrated and explored.

工程地质学领域现已达成共识：完备的场地岩土模型（ground model）对于任何工程建设项目的成功落地均至关重要。该场地岩土模型需涵盖场地地质、地貌与岩土工程要素，并阐明各类要素间的潜在相互作用，方可为参与特定项目的工程师或地质学家提供实用价值。法国阿尔卑斯山格勒诺布尔周边区域，便是阐释上述理念的理想野外研究场地。该区域内分布有多处大型工程构筑物，直观凸显了规范工程地质勘察与构建精细化场地岩土模型的重要性：唯有通过此类工作，方能厘清复杂场地的岩土性状与工程表现。该区域集中展现了岩土工程灾害、场地易损性及相关风险等核心议题，同时也彰显了全面掌握基岩与表层岩土条件的关键意义。本野外指南详细介绍并探讨了多个关键研究点位，可在此完整展示与探究上述各类议题。
