  • There is a great area of loses along the Yili trunk ditch in Xinjiang province. The collapsibility of the losses with water has a great impact to construction in the region. On the basis of many tests, a detailed analysis about the grade, the initial pressure and the depth of loess collapaibilty, and the degree of loess collapaibilty along the ditch built by excavating is given in this paper. A deep analysis is also made to the collapaibilty along the ditch built by piling considering the unsaturation of loess. It reveals the grade of collapssility is Ⅰ~Ⅱ and belongs to the non-self-weight collapse loess in the field along the ditch and the loess would lose collapssility after being compacted. It is also found that the loess would lose its collapssility only by permutation and drainage. Other measures are not needed to remove the loess collapssility.
