乌蒙山区红层软岩滑坡地质演化及灾变过程离心机模型试验研究

红层是一种分布广泛，性质特殊的易灾地层组合，其灾变基础科学问题已成为工程地质学科领域迫切需要解决的前沿课题之一。我国红层分布区工程规模巨大，灾变问题突出，主要表现为地质灾害、工程病害、生态损害3大灾变类型，使得红层地区经济社会可持续发展面临着前所未有的灾变危害与风险，严重威胁着一系列国家重大战略的实施。传统红层灾变理论和防控技术难以适应复杂条件下人地失调带来的重大挑战，亟待突破。本文旨在通过对国内外研究现状分析、对基础性科学问题的深入思考与系统梳理，阐明中国红层灾变研究概况，分析红层灾变基础研究的国际学术前沿问题，提出红层灾变基础研究亟待解决的3个关键科学问题，阐述了主要研究思路与内容及方案。这些思考寄期于支持破解红层灾变地质基因、成因机理、韧性协调防控等难题，以保障红层地区国家重大战略的高效实施，保障人居安全、生态文明建设和社会经济可持续发展，使得我国红层灾变研究占领国际前沿高地。

Centrifugal tests on geological evolution and sliding process for red-bed soft rock landslide in Wumeng Mountain area

Red beds serves as the widely distributed and unique-characterized disaster-prone strata. Its catastrophe research is one of the cutting-edge topics in the field of engineering geology. The scale of the red beds distribution area in China is tremendous, and its disasters are prominent. It is mainly manifested in the three major types of geological hazards, engineering diseases, and ecological damage. They make the sustainable economic and social development of the red beds area facing unprecedented disaster hazards and risks. They seriously threaten the implementation of major national strategies. However, it is difficult to adapt to the major challenges caused by the disaster theory and prevention and control technology of traditional red beds, which need to be solved urgently. Therefore, in this study, we clarify the overview of red beds around home and abroad through detailed investigations, in-depth thinking, and systematic sorting out. Then, we analyse the current status and development trends of the basic research of red beds disaster, and clarifying the three major international cutting-edge scientific issues. The three key scientific issues that need to be resolved in the basic research of red beds are proposed. Simultaneously, the main research ideas, contents, and solutions are explained. These thoughts are supporting problems such as red beds geological genes, cause mechanisms, toughness coordination prevention and control of the disaster. It can ensure the efficient implementation of major national strategies in the red beds area, ensure the safety of human settlement, the construction of ecological civilization, and the sustainable development of social economy. Furthermore, it can lead the world red beds catastrophic research.
