Evaluation of the collapsibility risk of loess based on oedometer test results

摘要

34 oedometer tests were performed on loess specimens to analyze the development of theirrncollapse. The stress range that causes the collapse of soil’s structure is determined, and its dependence onrnmoisture content is discussed. 11 out of 34 tests were performed with water flooding. These tests werernperformed on soil specimens having different initial moisture content, and the effect of the stress level atrnwhich the specimen is flooded is analyzed.
