珊瑚礁钙质砂工程力学特性研究综述
|
摘要
随着海洋资源的开发利用特别是21世纪海上丝绸之路的快速发展,在丝路沿线基础设施建设过程中遇到了一系列的珊瑚礁岩土工程问题。本文综述了珊瑚礁钙质砂工程地质研究进展,介绍了颗粒破碎对钙质砂压缩特性和应力应变关系和本构模型的影响,整理了地基处理的方法。在此基础上,提出未来开展钙质砂研究时可以考虑含泥量和颗粒级配因素;在开展应力应变研究时,可尝试建立考虑胶结力和石油、酸雨等污染物对钙质砂的影响的新的本构关系;以及适应吹填钙质砂的新型地基处理方法—强夯-振冲分层联合法。
With utilization of marine resources and the rapid development of 21 st-Century Maritime Silk Road,a series of coral reef geotechnical problems encountered during the construction of the infrastructure along the Silk Road. This paper reviews the progress of engineering geology of coral reef calcareous sand, the effects of particle crushing on the compressive properties and stress-strain relationship,constitutive model of calcareous sand are introduced and finishing the method of foundation treatment. On the basis of this,it is suggested that the future scholars can consider the mud content and the grain gradation factor in the study of calcareous sand particles. Besides,in the study of stress and strain,we can try to establish a new constitutive relation considering the effect of cementing force and pollutants on calcareous sand. We can also try new method of foundation treatment-dynamic compaction-vibrating stratification combined method.
