Meanwhile,the characteristic or the relationships for the strengthening effect,deformation orderliness,tamping-energy,tamp frequency,tamp influence depth and the horizontal influence distance via a novelty in.

By simulating the excavation course of foundation pits and starting with the change of stress field,the regularities of remanent strength and static earth pressure of viscous soil mass under excavated plane are analyzed so that the influence depth due to soil mass excavation unloading may be determined.

Based on the analysis of stress path characteristics,influence depth of reinforcement and mechanism of consolidation deformation,this paper reveals the characteristics of stress and deformation in the bridge-slope subgrade reinforced by vacuum well-point dewatering combined with equal preload.

By means of the stress state analyses on the rock mass surrounding openings , we studied the stress state of rockburst and the effective depth of rockburst .

The method estimates projective depth of line measure matrix,does SVD and applies transform to make the result validate.

T he paper investigatest hea lgorithms to compute the deepest point based on the projection depth and the spatial depth, and through simulation we can conclude that these algorithms are very exact and simple.

The paper improved Bayes linear and nonlinear discriminant analysis through replacing sample mean and scatter matrix by robust estimates based on the projection depth.
