摘要

采用高压固结试验，研究珊瑚礁沉积碎屑物试样在固结、回弹过程中的变形特性以及在不同加载方式、含水条件下的颗粒破碎情况，分析含砂量对变形的影响以及不同试验条件下的颗粒破碎规律。研究结果表明，不同的含砂量使砂、砾在试样固结时起到的作用不同，导致试样变形规律存在差异；加载方式、含水条件等对颗粒破碎影响显著，并在颗粒破碎结果分析中发现，0.25 mm是颗粒破碎时相对稳定的粒径，是研究钙质砂颗粒破碎的一个重要粒径界限，其结果对于将钙质碎屑物作为稳定的填筑材料、提高珊瑚礁地基稳定性等具有实用价值。

Abstract

Researchers used high-pressure consolidation tests to study the deformation law of calcareous clast of coral reef during consolidation and rebound stages

as well as particle breaking conditions under diverse loading ways or saturated conditions. The results show that different contents of sand and gravel in sample play different roles during consolidation

which lead to different deformation laws. Loading method and aquiferous condition show appreciable impact too. Analysis of particle breakage result shows that 0.25mm is the relatively stable particle size during breaking

which is an important particle bound in particle breakage study. This finding is of great significance on using calcareous clast of coral reef as a stable packing material and increasing the stability of it.
