The mineralogical composition and textural features of rocks are principal controls on rock engineering properties. A challenging rock material for engineers is represented by the evaporites, typically composed of gypsum, anhydrite and halite-rich sediments. In Abu Dhabi city vicinity, the bedrocks consist of evaporites and carbonate rocks that are partly covered by recent eolian sands and fluvial deposits. This contribution characterizes the petrographical and geoengineering properties of evaporitic rocks from Abu Dhabi city vicinity, United Arab Emirates since there are no published data available. Construction sectors in this city vicinity regularly face technical difficulties and foundation instabilities associated with evaporite bedrocks supporting foundations of buildings and infrastructures due to expansion and dissolution of evaporites. The data collected in this study includes (i) the mineralogical composition and textural features of the evaporites, and (ii) a list of geoengineering characteristics of evaporite rocks aimed to assist engineers and decision makers in resolving foundation problems at construction sites. Petrographic descriptions were obtained using polarized-light microscope, scanning electronic microscope (SEM), x-ray diffraction (XRD) and x-ray fluorescence (XRF) methods. Rock mechanical tests included Unconfined Compressive Strength (UCS), Point Load Index (PLI), Indirect Tensile Strength (ITS), Schmidt Hardness Value (SHV_RB) and Slake Durability Index (SDI), performed according to the International Society of Rock Mechanics (ISRM) and the American Society for Testing and Materials (ASTM) standards. Varying degrees of correlation (weak to strong, positive to negative) exist between the geoengineering parameters, probably reflecting the influence of petrographical properties of evaporitic rocks on these parameters.

岩石的矿物组成和结构特征是岩石工程性质的主要控制因素。对工程师来说具有挑战性的岩石材料是蒸发岩，通常由石膏、硬石膏和富含岩盐的沉积物组成。在阿布扎比市附近，基岩由蒸发岩和碳酸盐岩组成，部分被最近的风积砂和河流沉积物覆盖。由于没有可用的公开数据，这一贡献描述了来自阿拉伯联合酋长国阿布扎比市附近的蒸发岩的岩石学和地球工程特性。由于蒸发岩的膨胀和溶解，该城市附近的建筑部门经常面临与支撑建筑物和基础设施地基的蒸发岩基岩相关的技术困难和地基不稳定。本研究收集的数据包括 (i) 蒸发岩的矿物组成和质地特征，以及 (ii) 蒸发岩的地球工程特征列表，旨在帮助工程师和决策者解决建筑工地的地基问题。岩石学描述是使用偏光显微镜、扫描电子显微镜 (SEM)、X 射线衍射 (XRD) 和 X 射线荧光 (XRF) 方法获得的。岩石力学测试包括无侧限抗压强度 (UCS)、点载荷指数 (PLI)、间接拉伸强度 (ITS)、施密特硬度值 (SHV) (ii) 蒸发岩的地球工程特征清单，旨在帮助工程师和决策者解决建筑工地的地基问题。岩石学描述是使用偏光显微镜、扫描电子显微镜 (SEM)、X 射线衍射 (XRD) 和 X 射线荧光 (XRF) 方法获得的。岩石力学测试包括无侧限抗压强度 (UCS)、点载荷指数 (PLI)、间接拉伸强度 (ITS)、施密特硬度值 (SHV) (ii) 蒸发岩的地球工程特征清单，旨在帮助工程师和决策者解决建筑工地的地基问题。岩石学描述是使用偏光显微镜、扫描电子显微镜 (SEM)、X 射线衍射 (XRD) 和 X 射线荧光 (XRF) 方法获得的。岩石力学测试包括无侧限抗压强度 (UCS)、点载荷指数 (PLI)、间接拉伸强度 (ITS)、施密特硬度值 (SHV)_RB ) 和 Slake 耐久性指数 (SDI)，根据国际岩石力学学会 (ISRM) 和美国材料与试验协会 (ASTM) 标准执行。地球工程参数之间存在不同程度的相关性（弱到强、正到负），可能反映了蒸发岩的岩相特性对这些参数的影响。
