| Popis: | In the civil engineering practice, construction operations in loose and high compressibility soils require the application of compressed sand cushions. Recently, there has been a substantial decline in the use of compacted ground beddings in the practice of industrial and civil engineering. This can be partly explained by the weaknesses of the existing calculation methods that may often generate higher values of the size of compacted cushions (width and thickness) and, consequently, cause a substantial increase in their cost. It is noteworthy that the existing methods of calculation do not take account of strength and deformation characteristics of the cushion material in the course of identification of the cushion size and their operating bearing capacity.However, the studies implemented by different authors suggest the possibility of reducing the size of compacted soil cushions applied to loose and high compressibility soils. Therefore, the most effective are the pads reinforced by high-strength reinforcing elements (as geo-textile, geo-grids, etc.) The author elaborates on the possible methods of expanding the scope of compacted ground bedding in the practice of industrial and civil construction. The analysis of the findings of experimental and theoretical studies of compacted and reinforced soil bedding in loose soils is performedРассмотрены возможности расширения области применения уплотненных грунтовых подушек в практике промышленного и гражданского строительства. Приведен анализ результатов экспериментально-теоретических исследований высокоуплотненных, а также армированных высокопрочными геосинтетическими материалами грунтовых подушек в условиях слабых и сильносжимаемых грунтов. |
