Simple 2D Liquefaction analysis of pore water pressure dissipation method for detached house ground

Study of convergence confinement method curves considering pore-pressure effect

The design of underground spaces is mainly carried out using empirical, analytical, and numerical methods. The convergence confinement method (CCM) is an analytical technique that is widely utilized in analyzing the stability of underground spaces. However, the main challenge in the stability analysis is the selection of an accurate constitutive model for rock mass, and particularly, its post-f...

Analysis of Ground Motion Parameters and Ground Liquefaction Prediction Using Gis for Kunming Basin, China

In this paper the geological structure and earthquake activity nearby Kunming Basin, Yunnan, China, have been studied. Different ground motion attenuation models used in Japan and in Yunnan, China, have been reviewed, and quantitative comparisons between the models have been made. The zonation of peak horizontal acceleration corresponding to a seldom happened earthquake and the zonation of the ...

Analytical analysis of ultimate ground pressure on tunnel support system

The ground reaction curve (GRC) is a vital component of the convergence-confinement method, which possesses many applications in the underground space designs. It defines a relation between the tunnel wall deformations and the ground pressure acting on the tunnel walls. Generally, GRC includes descending and ascending branches. According to many researchers, the descending branch trend for the ...

Estimation of pore water pressure in the body of earth dams during construction with intelligent models

One of the basic measures in managing the stability of earth dams is to accurately estimate the amount of pore water pressure in the body of the dam during and after its construction. In this study, three different models of artificial neural network (ANN), adaptive neural-fuzzy inference system (ANFIS) and gene expression programming (GEP) to estimate the pore water pressure in the body of Kab...
