1. The proposed method of analysis of the load-carrying capacity of an anchor on the basis of the strength of the plug-rock interface makes it possible to take into account more adequately the actual stress conditions at this interface in comparison with the schemes based on an arbitrary uniform stress distribution. 2. Failure of the rock within the limits …

Already in the 1970s, investigating the carrying capacity question in their book "Limits to Growth," Meadows et al. argued that in case of continuous unchanged growth in five basic sectors (population, industrialization, pollution, food production, and consumption of natural resources), humankind would have reached the natural limits of ...
stiffnesses of pile, sidewall rock and toe rock. It is simply not tenable to arbitrarily ascribe certain portions of load carrying capacity to the sidewalls and the base in accordance with notional allowable values. In other words allowable side shear and 4.1 DESIGN PARAMETERS Sidewall Shear Resistance Two paths have been taken In regard to the
Rock socketed bored piles are particularly advantageous for conditions in which rock is near the ground surface underlying weak layers. This paper aims to predicate the ultimate capacity of bored ...
Estimation of N σ: In the FELA framework, the load carrying capacity of the rock-mass, the upper-bound (UB) and lower-bound (LB) estimates of Q have been obtained using the limit analysis theorem. The average of UB and LB estimates has been further used to estimate the non-dimensional factor, N σ in a similar manner as described in the …

In all methods below, the pile is divided into segments based on changes in cross section, soil or rock layers and ground water level.
The carrying capacity definition is the maximum size of a population sustainable by a specific environment. When a population reaches the carrying capacity, the net growth rate is 0 0 0: the number of births equals the number of deaths (and the other factors affecting the number of individuals balance each other).. The population plateaus …
