摘要

摘要: 处置巷道中回填材料作为高放废物地质处置库工程屏障系统的重要组成部分，要求其具有一定的安装密度以满足其屏障功能。基于我国高放废物地质处置概念和回填材料设计概念，结合回填砌块和膨润土小球的参考设计，开展回填材料安装密度的影响因素敏感性分析，发现砌块干密度和砌块填充度为主导因素。在此基础上，结合回填材料安装密度的设计要求，通过分析36个可能的安装布置方案，提出满足要求的设计参数范围，为我国高放废物地质处置库中回填材料的相关试验研究提供技术参考。

Abstract: Backfill materials in disposal drifts are important engineering barriers in geological disposal repositories of high-level radioactive wastes; a certain installed dry density is required to meet its barrier function. Based on the concept of geological disposal of high-level radioactive wastes in China and the design concept of backfill materials, the sensitivity analysis of factors affecting installed densities of backfill materials by combining the reference design of backfill blocks and pellets was carried out. It was found that block dry densities and filling degree were the dominant factors. Then, combining the design requirements of the installed dry densities for backfills, feasible plans to meet the requirements were proposed on an analysis of 36 possible installation schemes. The study could provide technical reference to related experimental research of backfills in geological disposal repositories of high-level radioactive wastes in China.
