摘要：Highlights Brazilian tensile strength variation and acoustic properties of Beishan granite treated with high temperature were investigated. The scatter distribution of acoustic emission energy during loading follows a linear trend, with increasing orderliness as the treatment temperature rises. When the tensile stress at the crack tip, enhanced by thermal stress, exceeds the intergranular tensile strength, crack initiation, and propagation occur.

关键词：Investigation on hardrock breaking performance and auxiliary mechanism of picks assisted with bothsided highpressure water jets
摘要：AbstractDouble-wheel trench cutters display reduced efficiency while cutting through hard or extremely hard rock strata, leading to significant wear on their picks. A high-pressure water jet-pick combined rock-breaking method (HPC) for double-wheel trench cutters is proposed, addressing the challenges of low efficiency and high pick wear when cutting hard rock strata. The HPC mode integrates hi...

关键词：A review on rockburst prediction and prevention to shape an ontologybased framework for better decisionmaking underground excavations
摘要：AbstractWith underground engineering projects becoming deeper and more complex, the associated safety problems, especially rockburst, have increasingly increased. Despite decades of research, effective management of rockburst continues to be a formidable challenge in underground excavations. This study presents a scientometric visualization analysis of 2449 papers and conducts a comprehensive r...

关键词：Form and load transfer aspects of foundation systems Casebased implementation adaptation for buildings
摘要：AbstractConventionally, foundations have been classified as shallow or deep in routine civil engineering practice. However, due to recent developments, two other approaches, semi-deep and ground modification foundations, are now available, complicating foundation categorization. Accordingly, a new concept for foundation categorization is introduced in this paper based on insights into the theor...
