Analytical determination of the safe distance from pits and excavations for driving piles into the ground

Abstract

The theoretical determination of the safe distance from pits and excavations for driving piles into the ground requires taking into account a number of factors, including the mechanical characteristics of soil, the depth of pile driving, the size of the pit or excavation, etc. The safe distance should be sufficient to prevent collapse of the walls of the excavation and it is determined based on geotechnical analysis, modeling, and calculations using specialized software programs and methods. This allows for considering all the influencing factors and ensuring safety when driving piles and performing construction work. In this article, one of the partial, but practically important options is considered - determining a safe place for driving piles into the ground near excavations or the boundaries of digging a pit for neighboring buildings. With the use of a bipolar coordinate frame, a condition was obtained by the analytical method, which makes it possible to determine at what distance from the wall of the excavation it is safe to drive piles.
