| 摘 要： | 简要介绍了沪蓉国道主干线湖北省高坪-吉心段的喀斯特地貌特征，分析其发育和形成原因，并对区域喀斯特发育史作了研究。通过不同地层岩石的溶蚀性、喀斯特发育程度及地下水的赋存情况，区域水文地质条件及地下水和地表水的补给、径流、排泄运动关系，研究此区域的集中排泄和分散排泄两大喀斯特水系统的发育规律及规模，在此基础上探讨了喀斯特对路线工程的影响作用。

| Abstract: | This paper discusses the influence of the Karst development on the planning project in the western section of Hu-Rong Expressway.Firstly, the characteristic of the karst landform in the section from Gaoping to Jinxin of Hu-Rong Expressway is introduced,the cause of the Karst development is analyzed,and the development history of the regional Karst is studied. Secondly, the development regularity and the scale of two Karst water systems,centralization runoff and decentralization runoff system,are studied through the analysis of the development of the karst and the underground water stock of different strata,regional hydro-geologic conditions and the relation of recharge,runoff and discharge of the ground and underground water.Based on the characteristic of different Karst water system,the Karst landform and Karst water system influence is evaluated,and recommendations are given for use of different engineering methods.Finally,the main Karst system characters and their influence on the project is summarized.These results show that the Karst in the third section of the Jialinjiang complement is deep and the expressway line should be kept away from it. |
