Abstract: To precisely model the size dependencies in nanostructures, the surface effect and bulk effect are incorporated. From the physical point of view, size dependencies stem from not only the surface, but also the bulk. The ...

Abstract: Uniaxial compressive strength (UCS) and tensile strength are essential parameters of rocks, but the direct measurement of these two parameters is time-consuming and requires high-quality samples. As such, academics brought ...

Abstract: When urban subway lines pass under buildings, it is often necessary to carry out corresponding pile foundation detection work to ensure construction safety. However, detecting the distribution of piles with conventional ...

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 ...
