Compacted Loess

Compression-tension test and direct shear test are used to evaluate the shear behavior of remolded loess under different water content and different dry weight density. Through massive analysis of test data, it is found that the valves of c and φ determined by compression-tension test can be used to characterize the shear strength index of soil.

Soil Shear Strength

In geotechnical practice we often meet the case when soils need to be improved. Various methods for the ground improvement are used in the geotechnical practise. One from methods of soils improvements can use also fiber-shaped waste materials. Such as polyethylene terephthalate (PET) plastic bottles are profusely and widely produced, yet used little for engineering purpose, and the overwhelming majority of them are placed in storage or disposal sites.One form expected improvements is increase of soil shear strength parameters which can be obtained by various methods, including laboratory tests. Determination of soil shear strength parameters by DST is still extensively used. In this paper we will deal with soil shear strength parameters of soil without and with plastic chips and their uncertainty. Uncertainties of shear strength parameters of soil without or with plastic chips are not negligible.
