4. Calculation of effective schemes for strengthening pile foundations by contour reinforcement with hard elements

Good day, colleagues.
We are grateful to the respected reviewer for the work done and appreciate his
time. For comments, we inform you the following:
- In our work, the effectiveness of the scheme for reinforcing pile foundations with
contour reinforcement is determined by the coefficient of reduced material
consumption - the required volume of reinforcement elements to reduce
precipitation by 1 centimeter. The lower the coefficient value, the higher the
reduced efficiency of the amplification circuit. For a scheme with continuous
reinforcement on two opposite sides, the coefficient of reduced material
consumption is CRCM = 9.33. For a reinforcement scheme with intermittent
reinforcement along the entire perimeter, the coefficient of reduced material
consumption is CRCM = 8.40. Thus, the second scheme is more effective than the
first. The values of the coefficients are presented in Table 1 of our article. You can
also find an explanation of the concept of the reduced material consumption
coefficient in the text of the article.
- There is no doubt that the bearing capacity of piles depends on the tip term and
the lateral friction. When conducting a numerical experiment in the MIDAS
software package, we certainly took this well-known approach into account. All
schemes for reinforcing the pile foundation with contour reinforcement in the
article presented by us were calculated taking into account this fact.
In our opinion, the main scientific results obtained during the numerical
experiment were to determine the effectiveness of different schemes for
strengthening pile foundations by comparing their coefficients of reduced material
consumption. As well as determining the sequence of reinforcement of pile
foundations with an increase in the number of reinforcement elements - from one
circuit to another, which made it possible to apply effective reinforcement
structures in practice and save labor costs.
