“…14 As shown in Figure 6, the experimental result indicated that surface roughness dropped on the whole as the grinding speed increased. According to the least square vector machine algorithm (LS-SVM) 15 and experiment data, a group of prediction data could be obtained. Based on the GA-BP network algorithm, the single factor experiment data were used in training, the corresponding prediction data were obtained for the surface roughness in accordance with the grinding speed.…”

This article studied the relationship between surface roughness and surface micro hardness of the hard-brittle materials and the process parameters in quick-point grinding, and then established the prediction model for the surface micro hardness and surface roughness by the back propagation network which was an improved genetic algorithm. Through the experiments of the quick-point grinding of ceramics, surface roughness and surface micro hardness were tested, and reliability of the model was validated thereby. Based on the least square fitting of the experiment value and prediction value, the one-dimensional analytic model for surface roughness and surface micro hardness had been, respectively, developed in terms of grinding speed, grinder work-table feed speed, grinding depth, incline angle, and deflection angle as process parameters. Both the correlation test and experiment verification indicated that the model exhibited a high level of accuracy. The multivariate model of surface roughness and surface micro hardness can be constructed by means of immune algorithms and orthogonal experiment data. With the optimum objective of the minimum surface roughness and maximum surface micro hardness, a set of optimized process parameters was obtained using immune algorithms, and experiment verification proved that the error value was less than 10%.

“…Ground anchors are an important load-carrying part that is directly related to the safety of tower construction, economy and rationality 9 , 10 . The effectiveness of ground anchoring mainly depends on the interaction of soil and ground anchors, and its mechanical mechanism of load transfer is often originated from a potential displacement of the anchor or soil 11 . Accordingly, ground anchors can be divided into two types: active and passive.…”

To avoid waste from a large section space structure layout and deep burial, improve the structural strength and stability. Anchor technology is introduced, and combined with the advantages of the supporting wall, a new debris-flow grille dam is proposed. Starting from the force process and damage mechanism of the new debris-flow grille dam, the computation formula for the anti-pulling force and the total displacement is given. The anti-pulling force includes the sidewall frictional resistance of the anchor pier and the positive pressure of the front end face of the anchor pier. The total displacement includes three parts: the elastic deformation of the cable, the relative shear displacement between the anchor pier and the surrounding soil, and the compression deformation of the soil at the front of the anchor pier. Finally, the influence of soil parameters and anchor pier size on the anti-pulling force and displacement deformation of the anchor-pulling system is analyzed by examples, and the results are compared with the numerical results. The results show that the displacement deformation decreases gradually with increasing elastic modulus of the soil around the anchor pier and increases with increasing Poisson's ratio. The change in elastic modulus mainly affects the relative shear displacement of the anchor pier and soil and the compressive deformation of the soil at the front end of the anchor pier. Poisson's ratio has the greatest influence on the relative shear displacement of the anchor pier and soil. A larger anchor pier is not better; thus, it is wise to choose the economic design dimension. Theoretical and numerical simulation results are consistent, showing a linear growth trend. The results of this paper can further improve the theoretical calculation method of the new debris-flow grille dam, thus making it widely used in more debris flow control projects.
