摘要

    摘要
  • 摘要: 珊瑚礁砂作为一种特殊的地基填筑材料,其基本特性是结构疏松、压实难、压缩性大、承载力低,实际的工程应用还鲜有报导。结合沙特吉达RSGT码头修建项目,对红海珊瑚礁的矿物成分、基本物理力学性质开展试验研究,分析将珊瑚礁砂用作码头吹填地基填料的可行性,并采用振冲挤密法对该珊瑚礁砂地基进行加固处理。通过对比振冲加固前后地基的CPT检测结果,并利用振冲加固后的标贯SPT数据对处理地基进行沉降分析计算,得出该珊瑚礁砂料是一类工程性质较好的新型填料,填筑地基经振冲挤密后的加固效果显著,既经济又环保,特别适合于沿海岸珊瑚礁大量分布地区的港口码头造陆工程建设。
    Abstract: As a special foundation filling material, the coral reef sand has many basic characteristics, such as loose structure, difficult compaction and low bearing capacity, while the practical engineering application is rarely reported up to now. Based on the Saudi Jeddah RSGT wharf construction project, the mineral composition, basic physical and mechanical properties of the red sea coral reef are studied, and the feasibility of the coral reef sand as the hydraulic filling materials for foundation is analyzed. Furthermore, the method of vibroflotation to reinforce the coral reef sand is adopted. Through the comparison of CPT testing results before and after vibroflotation and the settlement calculation on the related foundation using the measured SPT data after vibroflotation, it is approved that the coral reef sand is a new kind of good filling materials for engineering. The reinforced effect is remarkable with the excellence of environmental protection and economy when it is used as filling materials for foundation after vibroflotation, which is especially suitable for the mass distribution of coral reef in the coastal areas of reclamation for port construction projects.
