摘　　要：本文分析了影响土水特征曲线的几个重要因素 ,在此基础上进行了大量的对比试验。通过试验 ,对土水特征曲线有了进一步的认识 ,并为土水特征曲线在工程中合理应用提出一些建议。最后 ,给出了一个适合于击实土的土水特征曲线的拟合模型 ,该模型具有简单。Some important factors which effect the characteristic curve of soil and water are analyzed herein and large amount of tests are conducted through which further knowledge of the said curve is obtained and proposals for reasonable applications of that curve to engineering are suggested. Finally, a fitting model the said curve suitable for compacted soil is provided which proves to be simple and practical.
