Історія створення та суть методу сумісних випробувань грунтів на пенетрацію й обертальний зріз

In the early 1960s, the USSR geotechnicians were given the assignment to develop the non-rock soils strength characteristics determining method in order to enable the operative tracked and wheeled vehicles passage estimation through the cross country. As a result of theoretical justification alongside the approbation in lab and field conditions by the group of professionals, there was developed a new method of soils strength investigation by the way of joint penetration and rotational cut testing. A new method of estimating soils strength undergone the overall investigation in different soils environments of the European part of USSR, particularly in Karelia – on stripped clays, center and the south of Ukraine – on sands and loess loams, Moscow region – on heavy clay soils. The prototype equipment allowed conducting the research in the cross country, shallow water areas, on the river beds and bottoms of the lakes
