摘要
卡洛特(Karot)水电站位于巴基斯坦吉拉姆(Jhelum)河上,工程区位于巴基斯坦东北部新近系弱胶结碎屑沉积岩分布地区,坝址及周边可利用混凝土骨料匮乏,难以获取工程所需混凝土骨料。对坝址周边近100 km范围地层分布开展了大量详细的调查研究,初步确立了可用料源,并根据料源分布制定了完备的勘察方案,采取特殊的勘察方法,以确保可用料料场的选取及勘察储量的精准度。总结回顾了卡洛特水电站混凝土骨料勘察的研究思路和方法,可为此类特殊地质环境条件下大型水电站工程的混凝土骨料勘察研究提供借鉴。
Karot Hydropower Station is located on the Jhelum River in Pakistan,and the project is in the distribution area of the Neogene System of weak gum-linked debris sedimentary rock in north-eastern Pakistan,and the dam site and surrounding areas are short of available concrete aggregates,making it difficult to obtain the available concrete aggregates required by the project.Through a large amount of detailed investigation and study of the formation distribution of nearly 100 km around the dam site,the available sources were initially determined,and a complete survey scheme was formulated according to the source distribution,and some special survey methods were adopted to ensure the selection of available material slots and the accuracy of the survey reserves.This paper summarizes the research ideas and methods of concrete aggregates survey of Karot Hydropower Station,and provides a successful example for the exploration and study of concrete aggregates for large hydropower projects under such special geological environment.
