    Abstract
  • The hydraulic fill foundation for coral sand is mainly composed of coral sand, coral branches and reef limestone fragments, which are dredged by trailing suction or cutter suction. The coral sand particles are uneven in size and irregular in distribution, with edges and internal pores. The long-term slow deformation of coral sand foundation is the key point of deformation control of buildings. Through the creep test indoor in 135 days, the creep characteristics of fine coral sand, quartz sand and cohesive soil are compared and analyzed. It is found that the creep characteristics of fine coral sand and quartz sand are similar, and they are obviously different from cohesive soil. Under lower load level, the long-term deformation of fine coral sand foundation can be estimated based on the conclusions from quartz sand.
