The Sedimentary Model and Quantitative Analysis of the Subaqueous Shrink-Cracks
-
摘要: 通过野外实地考察测试、室内实验分析、数据处理等,对水下收缩裂隙的形成过程、裂缝充填模式、定量分级、各参数之间的拟合关系、微小扰动对裂缝形成的影响等进行了详细讨论,并且建立了水下收缩裂隙产生的地质理论模型以及对未来研究方向提出的几点建议。这些对于定量描述裂缝形态、结构、变化规律,预测区域性裂缝规模、分布范围,判别区域沉积环境具有十分重要的理论意义和现实意义。Abstract: The subaqueous shrinking cracks have been studied in detail by the textual research and field observation, the laboratory analysis and data processing and so on, which includes the forming process, sedimentary models, quantitative grade, linearization of various parameters and influence of the minute disturbance, etc. The geological models of the cracks are also established and some suggestions and comments are put forward to future research in this field. All of these conclusions are significative to describe quantitatively the configuration and structure of the cracks and its changes, forecast the territorial dimensions and the distributed areas and differentiate the territorial geo-circumstantialities.
