江苏镇江城市三维地质结构模型的建立及其地质意义
Establishment of a three-dimensional geological structure model, and its signiifcance for Zhenjiang city in Jiangsu
摘要
Abstract
With the development and utilization of underground space in urban construction in Zhenjiang, the demand for information on the urban geological environment and the stability of the earth's crust has led to a rise in urban geological surveys. Urban geological survey results show that loose Quaternary sediment layers are present in each lithofacies zone, which can lead to delamination during driling. Based on these ifndings, we use a partition modeling method in this work to construct a three-dimensional geological model of the Quaternary geology for the ifrst time. According to the distribution of rock facies and the concealed fault, we have built a three-dimensional structural model of the geology. The model shows the vertical and horizontal distribution of the strata, the relationships between the phase transformations in the three dimensional space, and the inlfuence of the fault on the stability of the earth's crust. This model can not only display the sedimentary history of the formation, but can also be used as an important source of information to support construction in the city.关键词
