Hydraulic and strength performance of three cement-stabilized soils subjected to cycles of freezing and thawing
(NRC Research Press, 2015-03)
A total of 108 specimens were prepared to examine the hydraulic performance and strength performance of nine
different cement-stabilized soils under unexposed and freeze–thaw exposed conditions. Specimens from each mix ...
Characterizing Porosity and Diffusive Properties of Monolithic Cement-Based Solidified/Stabilized Materials
(2012-07)
This paper presents the application of a single reservoir diffusion test to determine both the effective porosity of a soil-cement matrix and the diffusivity of tritium through saturated, monolithic, cement solidified/stabilized ...
Evaluating Impact Resonance Testing as a Tool for Predicting Hydraulic Conductivity and Strength Changes in Cement-Stabilized Soils
(American Society of Civil Engineering, 2015)
In this paper the impact resonance (IR) test method is used as a nondestructive tool to examine the curing progression, freeze/thaw (f/t) resistance, and healing potential of cement-stabilized soils. Resonant frequency ...
Nucleation and arrest of dynamic slip on a pressurized fault
(2012-10)
Elevated pore pressure can lead to reactivation of slip on pre-existing fractures and faults when the static Coulomb failure is reached locally. As the pressurized region spreads diffusively, slip can accumulate quasi-statically ...
Numerical Analysis of Longwall Mining Layout for a Wyoming Trona Mine
(Elsevier, 2016)
At Solvay Mine, located in southwestern Wyoming, a subhorizontal trona seam is mined at depths of between 460-490 m using mechanized room-and-pillar and longwall mining methods. The stratigraphy at the mine generally ...
Statistical Sample Size for Quality Control Programs of Cement-Based Solidification/Stabilization
(NRC Press, 2015)
Sampling requirements for the quality control (QC) of cement-based solidification/stabilization (S/S) construction cells do not currently specify the sample size considering the accuracy of the estimated effective hydraulic ...
A Coupled MM5-CMAQ Modeling System for Assessing Effects of Restriction Measures on PM10 Pollution in Olympic City of Beijing, China
(2012-06)
In this paper, a coupled MM5-CMAQ modeling system was employed to investigate the PM10 pollution issue in Beijing, China, with a focus on assessing the effects of different restriction policies implemented during and after ...
Seismic and aseismic slip pulses driven by thermal pressurization of pore fluid
(2012-04)
There are several lines of evidence that suggest that thermal pressurization (TP) of pore fluid within a low-permeability fault core may play the key role in the development of earthquake slip. To elucidate effects of TP ...
Assessing the Effects of Land Use Changes on Non-Point Source Pollution Reduction for the Three Gorges Watershed Using the SWAT Model
(2013-09)
This study presents a new attempt of applying the hydrological model SWAT to the Three Gorges watershed in China for addressing its non-point source (NPS) pollution control issues. The model was calibrated and validated ...
