Root Cohesion Estimation of Riparian Trees Based on Model Uncertainty Characterization
Publisher: American Society of Civil Engineers
Abstract: The mechanical reinforcement effect of roots on soil shear strength is widely recognized and can be used in slope stability analyses based on the limit equilibrium or finite-element method. Although some advanced root ...
Improved Crack Resistance and Pore Structure of Cement-Based Materials by Adding EVA Powder
Publisher: ASCE
Abstract: The improved properties of ethylene-vinyl acetate (EVA)-modified cement-based materials have not been fully clarified, especially crack resistance and pore structure. The purpose of this research was to investigate the ...
Detection of Stationary Markovian Zones in a Geologically Heterogeneous Area
Publisher: American Society of Civil Engineers
Abstract: The stationary Markov process model is widely used to predict the geological conditions in tunnel excavation projects. However, the validity of the stationary assumption made in the model is questionable. The prediction ...
Numerical Analysis of the Three-Dimensional Dynamic Response of Railway Subgrade Induced by Heavy-Haul Trains Based on FEM Model
Publisher: American Society of Civil Engineers
Abstract: Research on the dynamic response of subgrades is essential for designing heavy-haul railway subgrades. Therefore, a dynamic stress field test was carried out on the Daqin Railway using a three-dimensional dynamic soil ...
Lightweight Design of Car Body Structure
Publisher: American Society of Civil Engineers
Abstract: The body-in-white finite element model of a type of domestic car was established. The effectiveness and the reliability of the numerical simulation model were verified by comparing the results of prototype vehicle’s ...
