Abstract
In the practice of designing anti-landslide pile structures along with the single-row walls find use in General multi-row two-row and retaining walls. This assumes that the second row of piles will greatly enhance the bearing capacity of retaining structure. The joint work of the piles in the rows and methods of their calculation are presented in a number of works of domestic and foreign. At the same time conditions the most effective use of the second row in the double row pile retaining walls remain to be studied. Since double-row pile retaining wall, the combined grillage represents a frame of flexible piles on an elastic Foundation, the load distribution between the piles from the existing on the wall of landslide pressure will depend on the flexibility of the piles, the ordinates of the load from the landslide pressure on the first row, the soil properties of landslide slope. To determine the valid picture of the work of anti-slide pile structures was tasked to establish the role of the second row in the work of double-row pile retaining walls. The article presents the results of analytical studies frame construction flexible piles, the combined grillage hard, perceiving landslide pressure. Effective capacity utilization of the second row of piles was assessed using the utilization of the bearing capacity of piles second through 4,000 different designs double row of walls made of piles of various cross-sections, length, their reinforcement, the depth of application of landslide pressure, as well as with different variants of soil conditions. Due to the significant complexity of the implementation many variants of the analytical calculations were carried out with the use of computers.
