Prediction Model for Performance Evaluation of Tunnel Excavation in Blocky Rock Mass
(American Society of Civil Engineers, 2018)The response of tunnel excavations in blocky rock mass is dominated by the presence of discontinuities. However, many of the studies reported in the literature consider these geological features in a simplistic manner by ... -
Experimental Study on Pore Structure and Mechanical Properties of Stratified Coal
(American Society of Civil Engineers, 2017)The most striking feature of liquid nitrogen (LN2) fracturing is to drastically reduce the temperature around the rock when LN2 is injected into the reservoir. The strong thermal gradient can significantly induce the ... -
Wedge-Failure Analysis of the Seismic Slope Using the Pseudodynamic Method
(American Society of Civil Engineers, 2017)In the past, the pseudostatic method was the most common method used to evaluate stability of the slope under seismic loads. Through the method, static forces acting on the center of gravity of a sliding body are used to ... -
Determination of the Geomechanical Parameters and Associated Uncertainties in Hydraulic Fracturing by Hybrid Probabilistic Inverse Analysis

Numerical Investigation of the Circumferential Stresses around Boreholes during Horizontal Directional Drilling
(American Society of Civil Engineers, 2017)Borehole stability during horizontal directional drilling is one of the most important issues affecting success of pipe installations using this technique under roads, railways, and other obstructions. Two failure mechanisms, ... -
Predicting the Earthquake-Induced Permanent Deformation of Concrete Face Rockfill Dams Using the Strain-Potential Concept in the Finite-Element Method
(American Society of Civil Engineers, 2017)Presented in this paper is a modified strain-potential method for the prediction of earthquake-induced permanent deformation of concrete face rockfill dams (CFRDs). The concept of decomposing the total strain of rockfill ... -
Equivalence between Bearing-Capacity, Lateral Earth-Pressure, and Slope-Stability Problems by Slip-Line and Extremum Limit Equilibrium Methods
(American Society of Civil Engineers, 2017)Classically, lateral earth-pressure, bearing-capacity, and slope-stability problems are considered separately, although these problems are all related to the ultimate limit state of a system. The authors see that these ... -
Finite Layer Formulations for Land Subsidence due to Groundwater Withdrawal
(American Society of Civil Engineers, 2017)A finite-layer method (FLM) based on consolidation theory is presented for land subsidence due to groundwater withdrawal. The groundwater flow in aquifer systems and the displacement within soil skeletons are approximated ... -
Analytical Solution for Bolted Tunnels in Expansive Loess Using the Convergence-Confinement Method
(American Society of Civil Engineers, 2018)Ground reinforcement using bolts is effective for underground excavations. The ground response of expansive loess tunnels with bolt reinforcement remains poorly understood. Therefore, this paper proposes an analytical ... -
Innovative Method for the Integral Sliding Stability Analysis of Filling Media in Karst Caves and Its Applications in Engineering
