| 摘 要： | 黄土的力学性质对黄土地区的工程建设至关重要。通过对兰州地区的黄土在天然含水状态下用不同的试验方法测得了其力学参数。根据室内直接剪切试验和原位试验结果,进行比较分析发现:用不同的试验方法测得的同一类黄土的力学参数值有所差异,而且原位试验比室内试验所测得的值偏大,尤其是剪损时的应变值,同类黄土在相同正压力下的原位试验值是室内直接剪切试验值的2

| Abstract: | The mechanical characteristic of loess is vital for constructions in loess areas.In this paper,mechanical parameters of loess in Lanzhou are tested by different experimentations under natural water content.Based on the data of a large number of loess tests of direct shear indoor and in situ direct shear,the results have some diversity tested by different experimentations.Furthermore,the result tested in situ is great than the tested indoor.Especially the strain of shear damaged,the result of the same loess ... |
