摘　　要：济宁市主城区在工程建设活动中积累了大量岩土工程勘察数据,因缺乏统一的岩土工程勘察地层标准,限制了这些宝贵的数据资源整合与共享。文章通过对“济宁市城市地质调查”项目施工的382个工程地质钻孔数据及“济宁市环城高架”等212个建设项目的岩土工程勘察数据进行系统的分析研究,开展了60 m以浅地层的系统梳理和划分工作。根据沉积时代、成因类型与沉积环境、物质成分与结构特征和物理力学指标,60 m以浅地层可划分为10个工程地质层组。依据地层年代、成因类型、岩性、颜色、物理力学性质等地质特征,进一步划分为24个岩土工程勘察标准地层主层,44个亚层。为了便于推广使用,圈定了分布广泛、便于识别的3个标志层:⑦层黏土、⑭层黏土和⑱层黏土。A large amount of geotechnical engineering investigation data has been accumulated of the main urban area of Jining City during various construction activities.However,the lack of a unified standard for geotechnical engineering investigation strata has limited the integration and sharing of these valuable data resources.This paper studies the data from 382 engineering geological boreholes conducted during the"Jining Urban Geological Survey"project and from 212 construction projects such as the"Jining Periphery Overpasses."A systematic review and classification are conducted of strata shallower than 60 meters.According to the age of deposition,genesis type and depositional environment,material composition and structural characteristics,and physical and mechanical properties,the strata shallower than 60 meters can be divided into 10 engineering geological layer groups.Based on stratigraphic age,genesis type,lithology,color,and physical and mechanical properties,they can be further subdivided into 24 standard main layers and 44 sub-layers for geotechnical engineering investigations.To facilitate promotion and use,this paper identifies 3 marker layers with widespread distribution and easy recognition:Layer⑦clay,Layer⑭clay,and Layer⑱clay.
