The clarification of the distributing disciplinarian and engineering properties of soft soil in Guyana Georgetown regions has important guiding significance for the design and construction of local projects. Based on Capital Airport Expansion Project, the physical and mechanical properties of the local soft soil are summarized and analyzed, Meanwhile, the applicability of the soft foundation treatment methods commonly used in China are discussed in conjunction with the major engineering geological problems, Finally, the effectiveness of the sand pile composite drainage plate method for the soft foundation treatment is analyzed. The research shows that: The distribute of soil layer along the depth are humus soil layer, muck layer, clay layer and medium fine sand layer; The humus soil layer and muck layer has the characteristics of high moisture content, high compressibility, low strength, high sensitivity and other unfavorable geology characteristics; After consolidation, the increase of shear strength of humus soil is not obvious, and the strength is still very low; The effectiveness of sand pile composite drainage plate for soft foundation reinforcement is verified, and the suggestions of remove the surface humus, appropriately prolong the preloading time, reduce the disturbance to the soil layer and some other rationalization proposal are put forward.
