玄武岩残积土的崩解性试验

论述了残积土的崩解性，并对两种不同风化程度下的玄武岩残积土进行了室内崩解试验，试验在原状土、烘干、风干三种条件下进行。试验结果表明，原状土样崩解速度较慢，风干土样崩解速度最快，烘干1h土样次之。同时，土样本身的矿物成分、颗粒大小、含水率等是影响土样崩解的重要因素，棕红色土样由于含有游离态氧化铁等因素，崩解速率大于黄褐色土样。

Disintegration Test on the Basalt Residual Soil

Disintegration of residual soil was discussed, and the indoor disintegration test was conducted on the two kinds of basalt residual soil under different weathering degree, on the conditions of the undisturbed soil, drying and drying. The test results show that the undisturbed soil samples collapse slower, air-dried soil samples fastest, drying soil samples after 1 h taking the second. At the same time, the mineral composition, the particle size and the moisture content of soil samples are the important factors that affect soil disintegration. For palm red soil sample, due to factors such as containing free ferric oxide, its disintegration rate is greater than the yellowbrown soil samples.
