Mechanism of strengthening of embankments on weak bases

Abstract
The geocell construction provides stability of a high embankment on a weak ground. When erecting a high embankment on weak soils, the geocell mattress is an effective alternative to the pile foundation or the replacement of soil, which reduces the cost and time of the erection. This technology is used in the course of new construction on weak and heterogeneous soils, including overlapping dumps and other waste storage facilities. The geo-cellular mattress forms a rigid platform with a thickness of 1 meter at the base of the embankment, which levels and reduces the amount of settlement, prevents the erosion of the weak foundation soil, increases its bearing capacity, accelerates the rate of soil filling. Thus, excavation and removal of weak soil is not required, cellular geomatress is mounted directly on a natural foundation, is filled with stone material and forms a rigid supporting structure. It has a cellular structure, assembled at the construction site from a rigid triaxially oriented geogrid Tensar TriAx® on the sole and vertical honeycombs of rigid uniaxial geogrid Tensar RE, connected by polymer rods or “bodkin”. The system of geocell mattress increases the overall stability of the embankment, reduces vertical and horizontal stresses in the ground, reduces the amount of settlement and ensures its uniformity.
