Development Patterns and Distribution of Karst Caves on Expressway Based on Geological and Hydrological Method

本研究基于地质、地貌和水文学方法,预测和评估了大永高速公路哈米德隧道的溶洞分布情况。通过文献综述总结了溶洞形成机理、发育规律及相关研究进展,收集和处理了研究区域的地质、地貌和水文数据。采用定量和定性相结合的方法,分析了不同地质条件下溶洞的形成特征,地下水对其发育的影响及演化规律。运用地质和水文学预测方法,预测了该高速公路沿线溶洞的空间分布情况。给出了高速公路沿线溶洞分布预测结果。对溶洞的危险性评估,提出了相应的工程规划和设计对策与建议。研究为该区域高速公路工程的科学规划与设计提供了参考依据。

This study predicts and evaluates the distribution of karst caves in Hamide Tunnel of Dayong Expressway based on geological,geomorphological,and hydrological methods.The formation mechanism,development laws,and related research progress of karst caves are summarized through literature review,and geological,geomorphological,and hydrological data of the study area were collected and processed.A combination of quantitative and qualitative methods is used to analyze the formation characteristics of karst caves under different geological conditions,as well as the influence and evolution laws of groundwater on their development.The spatial distribution of karst caves along the expressway is predicted using geological and hydrological prediction methods.The predicted distribution of karst caves along the expressway is provided.This paper provides corresponding engineering planning and design strategies and suggestions for the risk assessment of karst caves.The study provides a reference basis for the scientific planning and design of highway engineering in the region.
