摘要
论述了煤灰作为土质改良材料的可行性。围绕软弱土经改良后的压缩性和剪切强度的变化,采用不同混合比的土样品进行了一系列的压缩试验和三轴剪切试验。试验结果表明,随着灰土比例的增加,样品的最大干燥密度芽剪切强度增加,固结系数及次固结系数减小。
The feasibility of coal ash used as soil improvement material is studied.To investigate the effect of coal ash on the compression and strength characteristics of improved weak soils,consolidation tests and triaxial compression tests are carried out with soil samples of various mixing ratio.The test results show that maximum dry density and shear strength increase and consolidation coefficient and secondary consolidation coefficient decrease with the increase of the percentage of coal ash.
