摘要
突发地质灾害事件应急响应具有社会聚焦性和时间紧迫性,处置决策离不开科学高效的技术支撑,数值模拟技术具有成本低、效率高、且能够方便考虑多种不同工况等优势。而目前对突发地质灾害应急数值模拟技术的研究尚未开展,同时常规数值模拟囿于技术条件等原因,对应急地质灾害技术的支撑实践效果十分有限。为此以滑坡灾害为例,在临滑稳定性研判、变形失稳机理分析和滑动过程推演等数值模拟应用现状分析的基础上,通过与常规数值模拟的技术条件比较,初步提出应急数值模拟技术发展的关键问题。以期有助于应急决策辅助应用。
The emergency response of geological disaster emergency has the characters of social focus and time urgency. As we all know,disposal decision depends on scientific and efficient technical support, and numerical simulation technology has low cost,high efficiency,and the advantages of the convenient to consider a variety of different conditions and so on. Literature study suggested that the numerical simulation technology analysis of geological disaster emergency is still insufficient,because of the shortage technical condition,the conventional numerical simulation can not support the practice efficiently. In this paper,landslide has been discussed in three aspects such as the sliding stability analysis,the analysis of deformation and instability mechanism and the sliding process deduction. Through the comparison with the conventional numerical simulation technology,the development of emergency numerical simulation technology are put forward preliminarily. At last,wish the study will be helpful for emergency decision aid application.
