Genetic programming has been widely used in the engineering field. Compared with the conventional genetic programming and artificial neural network, geometric semantic genetic programming (GSGP) is superior in astringency and computing efficiency. In this paper, GSGP is adopted for the classification and regression analysis of a sample dataset. Furthermore, a model for slope stability analysis ...

A systematic quantitative methodology for the reliability analysis of stability of rock slopes is presented. A sliding mass resting on an inclined plane and composed of two blocks separated by a vertical tension crack is considered, and a disjoint cut-set system formulation is proposed, with each cut-set corresponding to a different failure mode of the slope. Methods for the evaluation of the s...

ABSTRACT The issue of environmental protection has led researchers to pay serious attention to waste tires. Civil engineers have found that waste tires can increase bearing capacity, earth slope stability, and other useful applications in civil engineering. In this paper, a series of experimental modeling have been performed to investigate the effect of waste tires on increasing the stabi...

In slope engineering, soils are commonly at unsaturated state. The question of how to apply unsaturated soil mechanics theory to the slope stability analysis has become a hot spot in today’s geotechnical engineering research. Based on the experimental research of how shear strength of residual soil varies with water content, reasonable computation modules can be created. By using limit equilibr...

Original scientific paper The cutting of a high-slope is a complex nonlinear system that is random, fuzzy and variable. Stability evaluation for it from both qualitative and quantitative perspectives is essential in disaster management. This study firstly conducts the engineering experience analogy, giving a qualitative description of the stability of the slope. Then the cutting slope stability...

This paper addresses some performance limits of the kneed and non-kneed passive-dynamic walking machines discovered by McGeer [10, 11]. Energetic inefficiency is measured by the slope γ needed to sustain gait, with γ = 0 being perfectly efficient. We show some necessary conditions on the walker mass distribution to achieve perfectly efficient walking. From our experience and study of a simpler ...

Mapping of landslide susceptibility in forested watersheds is important for management decisions. In forested watersheds, especially in mountainous areas, the spatial distribution of relevant parameters for landslide prediction is often unavailable. This paper presents a GIS-based modeling approach that includes representation of the uncertainty and variability inherent in parameters. In this a...

In the process of wall design for open pits, a number of steps and levels of analyses are required, from local bench design to overall stability of the walls, to evaluation of the design performance and calibration of parameters through back-analysis. This process requires the use of a variety of methods of analysis and software ranging from limit equilibrium methods to more involved numerical ...
