Entry points for underground cavities in Vienna

Since 2010, the State, in the Department of Vienna, has initiated a series of inventories to assess “cavitated” risk in its territory.
In 2010, cavity inventories were carried out by the Bureau de Recherches Géologique et Minières (BRGM). They are based on a national methodology that allows data to be collected from the consultation of available bibliographical references as well as the questioning of all the municipalities of the department.The information concerning all the listed cavities can be found on the site: www.georisques.gouv.fr
On the basis of this inventory established in 2010, more detailed inventories were carried out on a selection of municipalities. These studies, conducted by the BRGM, consist of identifying and summarising the cavities present in each communal territory and assessing the issues impacted on the surface.
This work has made it possible to characterise the stakes above the voids caused by the presence of cavities. Surface issues have been identified for each entry. The areas impacted by the cavities will need special attention from the local authorities in order to best control urbanisation in under-cavated areas.

In addition, other studies carried out in the context of specific procedures (e.g. development of PPRs, geotechnical studies related to development projects, etc.) provide insight into the existence of underground cavities that have not yet been inventoried. The inventories cannot be exhaustive.

This table contains the entries of the underground cavities identified during the various detailed inventories and other studies carried out in the department of Vienna.

自2010年起，维也纳省（Department of Vienna）的国家主管部门已启动一系列清查工作，以评估辖区内的‘空穴化’风险。
2010年，法国地质与矿业研究局（Bureau de Recherches Géologique et Minières, BRGM）牵头开展了空穴清查工作。该工作采用一套国家级统一方法体系，通过查阅现有参考文献资料、问询该省所有相关市镇的方式收集相关数据。所有已登记空穴的相关信息均可通过官方网站www.georisques.gouv.fr查询获取。
基于2010年完成的首次全域清查，研究团队针对筛选出的部分重点市镇开展了更为细致的专项清查工作。此项由BRGM主导开展的研究，旨在识别并汇总各市镇辖区内存在的地下空穴，并评估其对地表造成的各类影响风险。
本次工作得以明确地下空穴引发的地表风险特征，并为每一处空穴条目标注了其所波及的地表范围。针对受空穴影响的区域，地方主管部门需予以特殊关注，以最优管控空穴多发区域的城市化开发活动。
此外，在特定程序框架下开展的其他研究（例如风险预防规划（PPRs）编制、开发项目相关岩土工程研究等），也揭示了一批尚未被纳入本次清查范围的地下空穴。由此可见，本次清查无法做到完全覆盖。
本数据集收录了维也纳省历次细致清查及其他相关研究中识别出的全部地下空穴条目。
