摘　　要：为研究海水侵蚀条件下我国南海研究区珊瑚岛地层渗透溶蚀特征,室内展开了不同密实度、pH值条件下的珊瑚砂渗透试验。研究表明:①在相同的pH值条件下,珊瑚砂的渗透系数和平均增长速率随着密实度逐渐降低。②侵蚀海水的酸性越强、pH值越低,则其对土体的渗透溶蚀特征越明显,珊瑚砂的渗透系数越大。To study the permeability and dissolution characteristics of coral island strata in the study area of the South China Sea under seawater erosion,coral sand permeability tests under different compactness and pH values were carried out in the laboratory.The results show that①under the same pH value,the permeability coefficient and average growth rate of coral sand gradually decrease with the compactness.②The stronger the acidity of eroded seawater and the lower the pH value,the more obvious the permeability and dissolution characteristics of eroded seawater to soil and the greater the permeability coefficient of coral sand.
