岩溶盲谷地区大型水库的工程地质研究与实践

Research and practice on engineering geology of large reservoirs in karst blind valley area

摘要

岩溶盲谷地区其地势高峻，是修建大型水库天然资源之一，可实现发电、灌溉，也可实现南水北调或东水西调，对发展工农业有着极为重要的现实意义。然而在岩溶盲谷地区修建水库，特别是大型水库其工程地质条件和水文地质条件极为复杂，修建难度较大且工程造价也较大。通过本文以五里冲水库为例对建库方案的论证和推荐，且采用帷幕防渗处理方案建库的成功，在探索岩溶盲谷地区修建大型水库有一定的现实、指导和实践意义。

Abstract

The karst blind valley area is one of the natural resources for building large reservoirs, which can realize power generation, irrigation, and water transfer from south to north or east to west. It has extremely important practical significance for the development of industry and agriculture. However, the construction of reservoirs in karst blind valley area, especially large reservoirs, has very complicated engineering geological conditions and hydrogeological conditions, and the construction is difficult and the project cost is also large. This paper takes Wulichong Reservoir as an example to demonstrate and recommend the construction scheme of reservoir, and the success of using curtain anti-seepage treatment scheme to build reservoir has certain practical, guiding and practical significance in exploring the construction of large reservoirs in karst blind valley area.
