Features: This book comprehensively elaborates on the deformation characteristics and patterns of soft and extremely soft rock tunnels through systematic monitoring of information and the analysis and calculation of these data. It successfully guides the construction of the longest and largest excavated section of extremely soft rock tunnel in the country by utilizing these patterns. During the construction of the Tianshan Tunnel with a rock uniaxial saturated compressive strength of less than 0.5 MPa and a burial depth of 80 meters, based on the actual project conditions and drawing on the construction experience of nearly 200 km of soft and extremely soft rock tunnels built nationwide, the construction principle of "short blast holes, rapid support, and frequent measurements" was summarized. This achieved an outstanding construction performance in soft rock tunnel construction, with no collapse incidents during the construction process, a 6-month advance in schedule, a 60 million yuan reduction in investment, and excellent engineering quality. Through detailed data, this book systematically summarizes the construction methods and measures of the Tianshan Tunnel. It also organizes and lists some research findings and construction experiences on soft and extremely soft rock, presented as engineering cases, to provide references for tunnel construction in soft and extremely soft rock areas in China and serve as a reference for relevant engineering technicians.
