Calculation of an inclined foundation with anchors for building on a slope
Abstract
This article investigates the operation of an inclined foundation with anchors used as the retaining component in a carpet-structural scheme for building on a slope. The calculation scheme for an "inclined strip-anchor-slope" system and a hypothesis about linear hereditary creep of base soils make it possible to describe the system's behavior in the process of construction and operation of a structure in the form of a system of integral and algebraic equations. The problem of finding the optimum slope of the anchor hole and the corresponding maximum tension of the anchor cable is solved. An example of such calculation for an actually existing object proves the possibility and economic efficiency of using the foundation under consideration for a carpet-structural scheme of building on a slope.
... Wang et al. [15] believed that except for the coal pillar length, the increase of top width, bottom angle, and height is conducive to improving the supporting effect. Sorochan and Puzrin [16] analyzed the relationship between the optimal anchor hole position, the maximum tension of the anchor cable, and the inclination angle through algebraic equations. Based on the Bishop method, Rakishev et al. [17] analyzed the variation of slope angle and dumping height with different inclined angles of bedrock. ...
Dump in the steep area of the open-pit mine is essential for safe production. The bedrock with the bumpy-surface blasting method effectively improves the stabilization of the dumpsite. The effect of the ratio and dispersion degree on the deformation and failure of the dumping bench at the largely inclined area was analyzed. Based on the limit equilibrium method, the equation about the stability factor and the blasted region ratio was deduced. Virtual experiments were performed to address how the ratio and dispersion degree affect deformation and failure. The results showed that the stability factor is a quadratic function of the ratio of the blasted area. The increase in the ratio results in a drastic reduction of displacement, and the direction of displacement significantly changes. The rise in the dispersion degree effectively reduces the displacement and shear strain increment, and the failure mode changes. There is a specific value for the ratio and dispersion degree, making the displacement and shear strain increment little. The research on bumpy surface blasting in this paper provides the theoretical foundation for the dump construction at the site with the large dip angle.
