Moraine Soils is one of the gravel soils that sedimented by glacial transporting and melting which including debris and other loose deposits before glacial period. So moraine soils have particular characteristics of erosion

transportation and sedimentaion. Because the moraine soils always include clods

macadams

gravels and sands

maintaining minus-cementation or argillaceous half-cementaion state

poor water-stability and easy disintegration. Moraine soils have been generally regarded as a problem on engineering treatment. Important step must be taken to solve the problem to obtain the strength behavior conclusively. But this step must be based on large scale with the structure of the moraine soils. Considering this

undisturbed samples and same dry density

different moistures remoulded samples are taken to large scale direct shear tests. The result shows that the undisturbed moraine soils have some structural strength

and the strength of the remoulded moraine soils falls along with the moisture increases.
