Сумісна робота паль і ростверку у стовпчастому пальовому фундаменті. Ч.1 Вплив низького ростверку на роботу стовпчастого пальового фундаменту

Abstract

In the master's qualification work on the theme "Collaboration of piles and rafters in columnar pile foundation. Part 1: Influence of low rafters on the work of a columnar pile foundation ". Experimental studies on small-scale models and numerical-mathematical modeling of pile foundations for the determination of the proportion of rafters in load on the foundation were carried out. It has been determined that the bearing capacity of the rafters depends to a greater extent on the relative length of the piles and the axial distance between the piles. With an increase in the relative length of the piles, the proportion of rafters in the load on the foundation decreases. As the pile steps increase, the bearing capacity of the rafting plate in the columnar pile foundation also increases. In the technical part of the master's qualification work the architectural and construction solutions were developed, the calculation of the column pile foundation was made, according to the list and volume of work on the building of the building a calendar schedule and a construction master plan with the placement of temporary buildings were developed. In the economic part, the calculation of the pile foundation, taking into account the load bearing capacity of the rafters and calculated economic effect, which is 25%. In the section on safety of life and labor protection, calculations of natural lighting in the premises during construction of the building and determination of the coefficient of anti-radiation protection of the premises are performed.
