RISLong-Term Performance of Pile-Supported Ballastless Track-Bed at Various Water Levels
Publisher: American Society of Civil Engineers
Abstract: In recent years, the constructions of pile-supported ballastless track-bed have been developed rapidly in China. It appears important to assess the accumulative settlement of this kind of track-bed after years of operation, ...
Peridynamics Simulation of Water Inrush Channels Evolution Process Due to Rock Mass Progressive Failure in Karst Tunnels
Publisher: ASCE
Abstract: Water inrush is one of the most serious threats to the construction safety of karst tunnels. Numerical simulation is one of the important means of underground engineering research, which is of great significance for revealing ...
Identification and Location Method of Microseismic Event Based on Improved STA/LTA Algorithm and Four-Cell-Square-Array in Plane Algorithm
Publisher: American Society of Civil Engineers
Abstract: The key issue of microseismic (MS) monitoring technology is to detect MS events and accurately locate the MS source. On the basis of the traditional short-term average/long-term average (STA/LTA) algorithm, a new characteristic ...
