| 摘 要： | 沉降柱试验是进行吹填工程室内试验的一种重要方法,目前沉降柱一般用有机玻璃制成,沉降柱的尺寸也从10cm发展到30cm。但是已有沉降柱试验中对沉降柱试验的边界摩擦问题没有深入的研究。进行了吹填淤泥(纯泥和泥砂混合物两种)与有机玻璃之间边界摩擦试验,分析了边界摩擦对沉降柱试验的影响,并探讨了沉降柱尺寸的确定问题。

| Abstract: | Sedimentation column tests are important methods of laboratory to study the Silt sedimentation in the hydraulic filling engineering.The column is usually made of the polymethyl-methacrylate.The diameter size of columns is enlarged from 10cm before to 30cm recently.For the friction face between the silt and polymethyl-methacrylate has not been focused in the sedimentation column test.This paper introduces the shear test of the friction face is conducted between silt(with and without sand)and polymethyl-methacrylate,and its influence to sedimentation clolumn test and the reasonable size are discussed by the finite element code. |
