| 摘 要： | 众所周知，湿陷性黄土对工程潜在的危害是很大的。因此，对黄土地区的土样进行黄土湿陷试验很有必要。依托渭南某工程，对黄土取样进行室内试验，并取得相应的结果，再运用ANSYS软件对该地区黄土土样进行数值模拟，得出土样的湿陷起始压力，相对下沉系数，自重湿陷系数等相关数据，并与室内试验结果进行比较，两者基本吻合，说明了ANSYS软件对黄土湿陷试验进行数值模拟是可行的。

| Abstract: | As well known, collapsible loess is greatly potential harmful to engineering; hence it is verv necessary to carry out loess collapsibility test on the soil in loess regions. Based on a project in Weinan, the loess therein was sampled and tested in laboratory. Then the numerical simulation of the related test results was conducted with ANSYS software, by which the collapsing initiate pressure of loess, relative subsidence coefficient, coefficient of self-weight collapsibility and other relevant data were obtained. Through the comparison between the results calculated and tested, substantial agreement was found out, showing the feasibility of numerical sinmlation in loess collapsibility test with ANSYS software. |
