Abstract The shear strength is a fundamental property of soil material under structural loads. determination properties unsaturated soils challenging and time-consuming. Geotechnical predictive models can be utilized to assess the heaving soil. This study attempts propose evaluate parameters compacted These include angle internal friction associated with net normal stress (ϕ'), indicating rate ...

Frost heave of canal foundation soil is the main factor destroying system engineering in cold area. Restricted by technical and economic conditions, further evaluation frost heaving index large channel areas where needed. Based on field investigation relevant methods, several indexes such as water content, compaction coefficient, fine grain cumulative negative surface gas temperature, direction...

Science of evolution is the basic life and earth science (LES). It searches for mobilize process reasoning tow scientific poles: functionalist historical. Because it try together to reconstruct history living beings from their origins explain working biological mechanisms in this process. Therefore, studies must respect double polarization. In article, we analyzed programs studied subjects scie...
