英文摘要	The coefficient of lateral pressure at rest (k(0)) is a key parameter required to determine the horizontal stress distribution on subsoils. In this paper, k(0) was measured from consolidation test for calcareous and siliceous sand, and the effect of water contents on k(0) of calcareous sand was also discussed. Comparison of k(0) values measured and calculated based on empirical formulas were carried on. Results indicated that (1) the reduction rate of k(0) for calcareous sand with an increase in relative density was less than that of siliceous sand. The k(0) at low water content was generally smaller than that of siliceous sand, and it was similar to that of siliceous sand for high-water content; (2) the k(0) of calcareous sand increased with increasing initial water content initially, and then decreasing. However, the magnitude of variation was small. So the impact of water content on the k(0) of calcareous sand was limited; (3) the formulas proposed by Abdelhamid and Krizek (1976) for estimation of the k(0) was highly applicable to calcareous fine sand.
