“一带一路”战略的实施,工程建设将越来越多的涉及到珊瑚砂地基,而国内有关勘察地基设计规范中,尚未列出珊瑚礁类岩土,国内外学者对珊瑚砂地基特性特别是地基承载力的现场试验研究也不多。珊瑚礁经人工扰动后,形成粗细粒土混杂的混合土地基,珊瑚混合土地基工程特性的评价没有可供借鉴的实例和资料。通过现场载荷板试验与动力触探的对比分析,得到了荷载板合理影响深度,动探击数与珊瑚混合土地基承载力具有良好的相关性,并通过分析得到动探击数与地基承载力、动探击数与变形模量的经验公式,对类似工程及科研具有一定的参考价值。
“One Belt and One Road ” strategy implementation, engineering construction will be more and more related to the coral sand foundation, and the domestic design specifications for surveyed foundations, not listed coral reefs, domestic and foreign scholars on the characteristics of coral sand foundation There is not much field test research on foundation bearing capacity. Coral reef artificial disturbance, the formation of coarse and fine mixed soil mixed soil foundation, coral mixed soil engineering evaluation of the foundation there is no available examples and information. Through the comparative analysis of on-site load plate test and dynamic penetration test, the reasonable influence depth of load plate is obtained, and the dynamic exploration number has a good correlation with the bearing capacity of coral mixed soil foundation. By analyzing, the number of dynamic exploration and foundation bearing capacity , The number of dynamic exploration and deformation modulus empirical formula, for similar projects and research has some reference value.
