Shotcrete Tunnelling
For tunnels driven using conventional shotcrete methods, the construction process technology and the selection of suitable support measures are of great importance. This chapter begins by presenting the correlation of shotcrete tunnelling and other methods into rock classes. In the top heading process, the top heading is excavated first and the bench and invert are brought up behind as required. The various methods are shotcrete tunnelling, underpinning method, crown pilot heading method and shotcrete tunnelling with longitudinal slots. In zones with considerably lower rock strengths due to deep‐acting weathering or in loose ground particularly when the horizontal forces are high, the core tunnelling method with side headings (or side wall drifts) is advantageous. The chapter discusses the special processes using shotcrete such as ground freezing and grouting. It discusses shotcrete method in mining, and a new Italian tunnelling method (ADECCO‐RS). The chapter also presents a short outlook for further development.
