Summary and Trend Analysis of Research Progress on Granular Slope Geological Hazards

Abstract

There are a large number of granular slope mixture geological disasters in the alpine mountainous areas in western China. Their structural characteristics are significantly different from the general slopes. They have the characteristics of poor self-stability, high suddenness and strong recurrence. With the continuous development of the western region of the country, such geological disasters have received close attention from scholars at home and abroad. This article first summarized and analyzed the basic characteristics of the typical domestic granular mixtures slope accidents, and understood the basic characteristics of disaster. Then the domestic and foreign research progress from the aspects of governance measures were summarized. Finally, based on the summary of typical granular mixtures slope disasters and research status, the existing problems in the current research were analyzed, and the key points and difficulties of future research had prospected. The research results have important theoretical significance for the treatment of granular slope.

Experimental investigation of maximum impact force exerted by dry granular flows on a rigid barrier

“…3b). Several studies have been carried out to model granular flows against rigid barriers by performing indoor experiments (Faug 2015) and analogue simulations (Albaba et al 2015;Gray 2018;Xie et al 2021). Pudasaini et al (2007) performed a laboratory test and concluded that the maximum impact force is an important factor to consider when designing a rigid barrier.…”
