The limit equilibrium method (LEM) has been a main-stay of analysis for geotechnical engineers for decades. Applied typically in a 2-D plane strain condition the method has been extended in formulation to the method of columns in 3-D and is now gaining increased use in industry. The formulation of the 3-D method of columns has typically been presented in Cartesian coordinates and with the assum...

Slope stability analysis is an enduring research topic in the engineering and academic sectors. Accurate prediction of the factor of safety (FOS) of slopes, their stability, and their performance is not an easy task. In this work, the adaptive neuro-fuzzy inference system (ANFIS) was utilized to build an estimation model for the prediction of FOS. Three ANFIS models were implemented including g...

Apparent particle size grading is the most important characteristic of super-high dumping site. On the basis of the development of the HHC-CA model and on-site survey of granular size distribution, the slope model of current situation, had considered the features of particle size grading, was established according to a super-high dumping site. FLAC was used to analyze the slope stability of cur...

In steep soil-mantled landscapes, the initiation of shallow landslides is strongly controlled by the distribution of vegetation, whose roots reinforce the soil. The magnitude of root reinforcement depends on the number, diameter distribution, orientation and the mechanical properties of roots that cross potential failure planes. Understanding how these properties vary in space and time in fores...

Dynamic gait planning for humanoid robots encounters difficulties such as stability, speed, and smoothness. In most of previous studies, joints’ trajectories are calculated in 3D Cartesian space, then, introducing boundary conditions and using polynomials, the first and second derivatives of the motion are ensured to be continuous. Then, the stability of the motion is guaranteed using Zero Mome...

The relationships between geological features and rockmass behaviors under complex geological environments were investigated based on multiple intelligence classifiers. Random forest, support vector machine, bayes’ classifier, fisher’s classifier, logistic regression, and neural networks were used to establish models for evaluating the rockmass stability of slope. Samples of both circular failu...
