Abstract: Large deformation of the surrounding rock is a common geological hazard when excavating a new tunnel to be driven through soft rock, and this occurrence can severely interrupt the construction schedule and affect the safety ...

Abstract: The classification and real-time identification of surrounding rock grades are of great significance to guide tunnel boring machine (TBM) construction. Taking a water diversion project in China as the background, this study ...

Abstract: Reinforcement cage length has a significant impact on the bearing capacity of bored piles. Accurate measurement of the cage length provides an important guideline for judging pile quality. Currently, the electric method ...

Abstract: Due to their low strength, high compressibility, and collapsibility, loess deposits are susceptible to large deformation and landslides during tunneling. An objective, scientific approach to stability assessment is urgently ...
