Numerical Simulation for the Interaction between Soil and Cable in Deep Foundation Pit

2009 International Conference on Computer Modeling and Simulation, 2009
Simplified mechanical model can not reflect the real situation of the interaction between foundation and cables. Then numerical software FLAC3D is used to simulate the procedure of foundation excavation and cable reinforcement. Deformation responses of foundation are analyzed as well as the mechanical response of cables.

Displacement Back Analysis for Rock Parameters of Deep Foundation Pit

Applied Mechanics and Materials, 2011
Numerical analysis is effective means to evaluate deep excavation influence in the sensitive environmental condition, and it is key issues to choose the elastic modulus of rock parameters reasonably. Based on the finite element theory, the relation between rock mass elastic modulus reciprocaland and the objective function value is a quadratic function ...

SVM in Predicting the Deformation of Deep Foundation Pit in Soft Soil Area

2010 International Conference on Machine Vision and Human-machine Interface, 2010
Based on the measured deformation data series, future deformation value of deep foundation pit was predicted using Support Vector Machine (SVM) model in soft soil area. Gauss kernel function, Sequential minimal optimization arithmetic, and the parameter value of C ande were determined by testing.
