description: The subject of the graduate qualification work is "Stress-strain state of the shore foundations of bridge structures and foundations"
This work is devoted to the analysis of the stress-strain state of the foundation taking into account the action of additional lateral soil pressure from the action of the weight of the mound approach according to change â1 to SP 35.13330 "Bridges and pipes". Tasks that were solved during this work:
1. Identification of the factor of influence of various options of sequence of installation of designs of bases and embankments behind them on size of efforts in piles.
2. Estimation of values of additional efforts and deformations in piles of the bases of the bases arising from action of horizontal pressure of soil from weight of an embankment of the approach depending on various stages of production of works.
The work was performed by modeling road foundations in the PLAXIS 2D geotechnical software package. Depending on the height of the embankment of the approach and the sequence of works, different combinations of internal forces in the piles were obtained, as well as deformations of the nozzle and the support post. To test the bearing capacity of the piles on the material, taking into account the additional lateral pressure of the soil, strength graphs for driven piles were used. Modeling of the foundation elements was performed taking into account the stiffness of the full cross section of the piles, as well as taking into account the shutdown of the stretched zone of concrete, according to JV 63.13330 "Concrete and reinforced concrete structures"
As a result, the sequence of work plays a decisive role in the magnitude of the internal forces in the piles, arising from the influence of additional lateral pressure of the soil from the action of the weight of the mound approach.
The account of additional lateral pressure of soil from action of weight of an embankment of the approach has to be carried out for calculation and the analysis of movements of elements of a design of a support since Significant displacements occurring at suboptimal stages can lead, for example, to the reset of the span structure, or the closure of the main beams of the span structure, which will lead to unacceptable forces and deformations.
