Simulation of Stress-Strain State of The Reinforced Soil Foundation for Structures

Abstract

Therein there is formation of algorithms database of stress-strain state of reinforced soil foundations and optimizing the main parameters of the computer model. The analysis of the results of calculations for the foundation strip, slab and columar type on homogeneous and layered the basis.

Geomechanical Substantiation of the Parameters of Injection Fixing of the Soil Bases During the Liquidation of the Emergency Condition of the Structure

“…3, d). The location of injectors in this scheme is taken in accordance with the basic method and takes into account a number of previously obtained recommendations for similar objects, described in [14,15]. The adopted fixing scheme provides a reduction in economic costs and is consistent with the technology of repair and recovery operations for these design solutions.…”

Increasing Stability of Mine Surface Facilities on the Fill-Up Ground

“…The base was simulated from the top mark of the foundation with the specification of equivalent vertical pressure forces P, the horizontal load T and the bending moment from deformation of the support in the transverse direction M. Table. Based on the data given and the algorithms, described in the work [11], the main parameters of the model for the case under consideration were assigned: the width in the longitudinal direction b m1 = 41.0 m, in the transverse direction -b m2 = 31.0 m (taking into account the size of the pit and the foundation); height of the model is h m = 21.0 m. The boundary conditions in the form of restrictions of displacements are superimposed similarly to the models adopted in [11,12]. For the model in the longitudinal section, the load P was set by two forces of magnitude P/2 with a displacement of l = 0.6 m on either side of the side faces of the foundation, simulating the position of the support elements.…”

The study of stress-strain state of stabilized layered soil foundations

“…Soil massif consists of the upper (layer #1) and lower (layer #2) layers with specified physical and mechanical properties in accordance with examples of calculation [12][13][14] Formation of the database for the analysis was carried out by setting the increment of physical and mechanical properties of the massif soils in the range of relations E 2 / E 1 = 1…5 (Table 1) with various schemes of ground stabilisation by injection according to the recommendations adopted in the works [15,16]:…”
