| 摘 要： | 研究了黄土工程力学性质的变化及控制因素，由黄土与红色古土壤工程力学实验资料表明，黄土的承载力、压强度与抗剪强度小于红色古土壤，这是它们经受了不同成壤作用的结果，通过分析实验得出粘化作用强，土壤力学强度大，粘化作用弱，土壤力学经度小，黄土地层工程力学性质在垂向上具有明显波动变化规律，这种变化是黄土与红色古土壤发育时冷干与温湿气候的交替变化造成的。

| Abstract: | According to experimental material in engineering mechanics of loess and red paleosol, it is known that the bearing capacity, pressure resistance and shearing strength of loess are less than that of red paleosol, which is caused by different soil formation processes. Intense clay grouting give rise to great pressure resistance and weak soil formation processes do little pressure resistance. Fluctuation changes are vertical change law of engineering mechanics character of loess strata, which is brought about by the alternative changes between cold and arid climate and warm and moist climate. |
