洞渣制作机制砂石骨料的技术研究综述

Review of technical research on sand and gravel aggregate for cavern slag production mechanism

随着我国交通运输行业的快速发展,铁路隧道的建设量逐年攀升,也就导致了大量洞渣的产生,与此同时,也需要消耗巨量的砂石骨料。为了加强隧道洞渣的资源化利用,缓解隧道建设过程中洞渣处理困难与砂石骨料资源短缺的矛盾,重点总结分析隧道洞渣在不同开采方式下的特点,阐述洞渣母岩不同加工工艺和母岩岩性对洞渣骨料及混凝土性能影响,指出隧道洞渣在当今社会利用过程中的不足之处,为针对隧道洞渣进行更好的资源化利用提供理论参考。

With the rapid development of China s transportation industry,the construction of railway tunnels has increased year by year,which has led to the generation of a large number of cavernal slag,and at the same time,it also needs to consume a huge amount of sand and gravel aggregates.In order to strengthen the resource utilization of tunnel slag and alleviate the contradiction between the difficulty of slag treatment and the shortage of sand and gravel aggregate resources in the process of tunnel construction.Focus on summarizing and analyzing the characteristics of tunnel slag under different mining methods,expounding the influence of different processing technologies and lithology of tunnel slag host rock on the performance of tunnel slag aggregate and concrete,pointing out the shortcomings of tunnel slag in the process of utilization in today s society,and providing a theoretical reference for better resource utilization of tunnel slag.
