    Sammanfattning : Since the investigation of wear particles in rail transport started in late-1910s, the high mass concentration of these particles has raised worries among researchers concerned with air quality. However, effective action has yet to be taken because of lack of relevant knowledge. LÄS MER

  5. 29. Block stability analysis using deterministic and probabilistic methods

    Författare :Mehdi Bagheri; Håkan Stille; Charlie C. Li; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Block stability analysis; Model uncertainty; Joint relaxation; Partial factor; Sensitivity analysis;

    Sammanfattning : This thesis presents a discussion of design tools for analysing block stability around a tunnel. First, it was determined that joint length and field stress have a significant influence on estimating block stability. LÄS MER
