Grouting Material Development and Treatment of Water and Mud Inflow Caused by TBM Tunneling in Faulgineering. The common solving method is to disassemble the cutterhead and tunnel shield of TBM, which can result in the unstability of the surrounding rock in the process of disassembly. Grouting without disassembly is a practicable method to reinforce the surrounding rock and reduce water inflow. H

Traffic Data Characterization for Road Rehabilitation: A Case Study of the Korogwe-Mombo Road Sectiestimation of the traffic load spectra, as they cause the most structural damage to pavements. As part of the pavement design process, heavy vehicle volume and axle load surveys are typically carried out to assist with the accurate estimation of the cumulative traffic loading over a pavement design

Analytical Method to Evaluate the Stress State Within Vertical Backfill,aluating the stress state in backfill is a critical step for design of backfilled stopes. An analytical method to evaluate the stress is proposed in this paper. Nonuniform distribution of vertical stress is considered in this method. The trajectory of minor principle stress in the fill from the cent

Numerical Simulation of Surface Subsidence After the Collapse of a Mine,his paper, a computer model is used to predict surface subsidence after the controlled collapse of a coal mine at Naburn in North Yorkshire, England. Scarcity of data on the characteristics of deep underground distressed and caved zones around coal mining excavations makes the numerical prediction o

A New Method Based on PFC3D and Hierarchical Modeling for Pile Foundation Analysis,of finite element method, using smaller particles for concerned part and use larger particles for the part which is close to the model boundary. By adjusting the micromechanical parameters of the particles, the macroscopic mechanical properties of the soils constituted by different particle diameter
