5. A Deterministic Method for Evaluating Safety Factor of Deep Excavation Stability against Groundwater Inrush Equivalently Considering Soil Uncertainty.

Author

Abstract

In current design specifications for deep excavation, the determination of safety factors against groundwater inrush only considers the self-weight effect of soil mass at the bottom. However, the shear strength and its spatial variability in a cement-solidified bottom layer also plays an important role in safety factor estimation. Based on that, in this study, the strength reduction method was introduced into reliability analysis of deep excavation engineering, and the influence of shear strength and its spatial variability of cement-solidified soil on the stability of deep excavation is studied. Furthermore, a deterministic analysis method that can equivalently consider soil uncertainty is proposed and verified. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Nanoplate structure of TiO2 was synthesized by surfactant-assisted hydrothermal method. The existence of nitrate ion with a high concentration prohibited the rolling of the nanosheets and played the key role on the formation of nanoplates of titanate. After calcinations, the titanate was transformed into TiO2 nanoplates (anatase) of micrometer-size with 20–30 nm in thickness. [Copyright &y& Elsevier]
