摘要: 通过新泰市山水文园住宅小区场地断裂探查实例介绍对小区地基开挖时发现的一疑似活动断裂的地质地貌调查，结合工程勘探、高密度电法勘探、探槽开挖、断裂错断上覆地层分析等手段进行活动性鉴定，结果显示该新泰—蒙阴断裂为晚更新世中晚期活动断裂，运动性质为左旋走滑正断；评价了该活动断裂对建筑工程的影响，并为小区的规划布局和地基基础设计提出合理的意见和建议，是断裂活动性鉴定在规划设计和工程建设中的一个具体应用，取得了很好的效果。Abstract: Through a specific example as shan-shui-wen-yuan residential district in Xin-tai city, the study introduces the geological survey of the suspected active fault found in the foundation excavation of a new civil building. Combined with engineering exploration, trench excavation, high-density electrical prospecting, and analysis of the strata dislocations that covered the fault, we identified the activity of Xintai-Mengyin fault, and gave the following results:The Xintai-Mengyin fault is a mid late Pleistocene active fault and a left lateral strike slip positive fault. We evaluated the affections on buildings, and put forwarded reasonable opinions and suggestions for the planning layout and foundation design of the district. This study is a specific application of fracture activity identification in planning, design and engineering construction, and achieved good results, it is of reference to other related projects.
