摘要

山体滑坡和斜坡不稳对人类住区和基础设施构成重大风险。本研究旨在为伊朗德黑兰省山区绘制滑坡易发图。利用区域滑坡数据库，在区域范围内采用了岩石工程方法。采用半定量岩石工程系统方法，考虑了 10 个调节因素。该模型利用历史滑坡数据进行了验证，显示出很强的相关性。大多数滑坡发生在中度和高度易发区。地质单元，尤其是卡拉季地层的粘土岩层，与滑坡易发性有明显的关联。岩石工程方法绘制出了高度精确的易滑性地图。研究结果可为该地区未来的国土规划提供参考。

Landslide susceptibility zoning based on Rock Engineering System application to the Tehran case study

Landsliding and slope instability pose significant risks to human settlements and infrastructure. This study aims to develop a landslide susceptibility map for the mountainous regions of Tehran province, Iran. The rock engineering approach was employed at a regional scale, utilizing a database of regional landslides. The semi-quantitative Rock Engineering System method was applied, considering 10 conditioning factors. The model was validated using historical landslide data, showing strong correlation. The majority of landslides occurred within medium and high susceptibility zones. Geological units, particularly the Karaj Formation's claystone layers, displayed a clear association with landslide susceptibility. The rock engineering approach yielded a highly accurate susceptibility map. Findings can inform future territorial planning in the area.
