摘要
通过建立建筑工程所在区域的三维地质模型,建筑设计和施工人员可对复杂地质条件进行分析和研究,为城市建设提供技术支撑。基于盛京金融广场项目勘探钻孔数据及地层分层资料,采用GTP建模方法,根据钻孔数据中岩层接触关系,从新到老、自上而下逐层自动创建三维地层模型。经交叉剖切分析检验,建立的三维地质模型与实际勘探数据拟合度较好,准确客观地反映了研究区域内的地层地质条件。本文通过对三维地质模型进行研究,分析了研究区域工程地质条件及施工过程的潜在风险,提出了风险管控措施,可为建筑物设计、施工和风险防控提供科学决策依据,具有较高的推广价值。
Through the establishment of a three-dimensional geological model of the areawhere the construction project is located,the architectural design and construction personnel can analyze and study the complicated geological conditions,which could providetechnical support for urban construction.Based on the exploration drilling data and stratigraphic stratification data of Shengjing Financial Plaza Project,this paper uses GTP modeling method to create a three-dimensional stratigraphic model from new to old and top to bottom according to the contact relationship of rock formation in borehole data.Throughthe cross-section analysis,it is verifiedthat the established 3D geologicalmodel has a good fit to the actual exploration data.The experimental results accurately and objectively reflect the complex stratigraphicgeological conditions within the study area.This paper studies the 3D geological model,analyzes theengineering geological conditions of study area and potential risks of construction process,and proposes risk management and control measures,which can provide scientific decision-making basis for building design,construction and risk prevention and control,and has a high promotion value.
