An experimental and numerical comparative study on the uplift capacity of single granular pile anchor and rough pile in sand

Jerin Joseph et al.

Summary: The study found that the granular pile anchor (GPA) is more effective in resisting uplift forces compared to bored pile, making it a viable alternative for ground anchoring. Experimental model tests and numerical modelling were conducted to examine the performance of GPA and rough piles in sandy soils under various conditions, confirming the suitability of GPA as an economical substitute for other methods.

Experimental Study of the Effect of Axial Load on Stress Wave Characteristics of Rock Bolts Using a Non-Destructive Testing Method

Chuanming Li et al.

Summary: Traditional rock bolt inspection methods are limited and destructive. Non-destructive testing based on stress wave method enables fast and convenient quality detection. By applying axial loads on rock bolts and collecting stress wave signals, the study uses VMD decomposition and Hilbert-Huang signal processing to analyze the characteristics of stress waves. The results show that the stress wave amplitude decreases gradually with increasing axial load, and the method of calculating axial load based on stress wave time-domain amplitude is accurate and reliable.
