Abstract: Malan loess is a special water content sensitive geological deposit, of which the physico-mechanical and hydraulic properties change with obvious patterns under the softening action of water. Based on the test data of a large number of Malan loess carried out in Utrecht University of Netherlands and Lanzhou city of Gansu Province with different methods; here, we study the physico-mechanical properties of Malan loess. According to the results of loess tests in laboratory and in-situ, the geotechnical properties, some laws of water sensitivity and shear strength properties of Malan loess are discussed emphatically; and some important critical indices of Malan loess are put forward.

Key words: Malan loess, tests, physico-mechanical properties, collapse, critical moisture content, shear strength, characteristics
