摘要/Abstract

摘要：

斯里兰卡是海岛型国家, 是印度洋航线关键节点, 具有重要战略地位。文章分析了斯里兰卡独特的地质构造背景, 其地形起伏剧烈, 地质灾害频发, 且抵御能力脆弱, 历史上曾发生过多起地质灾害, 造成了重大人员伤亡和经济损失。针对地质灾害频发的问题, 本文提出了在沿海城市构建综合地质灾害监测平台的紧迫性, 并且详细介绍了地质灾害监测平台建设3个阶段的布设情况, 证明监测平台具有可行性。提出了斯里兰卡地块的构造演化机制和沿海城市浅层地质结构的稳定性是迫切需要解决的两个重要科学问题。利用采集到的最新地震数据, 聚焦斯里兰卡沿海地区地质构造与速度结构研究, 结合地质灾害的时空变化特征, 制定当地的地质结构稳定性评估标准, 为区域地质灾害和风险防范提供直接科学证据。利用岩石学、地球化学、地球物理、地质定年等多学科交叉手段, 建立更为全面的地质构造演化模型。

关键词: 地质灾害, 地质灾害监测平台, 构造演化, 浅层结构稳定性, 斯里兰卡

Abstract:

Sri Lanka, an island nation, holds strategic importance as a key node in the Indian Ocean shipping routes. This paper delves into the unique geological structure of Sri Lanka, characterized by steep terrain and frequent geological hazards, against a backdrop of limited preventive capabilities. Commencing with an analysis of these geological structure, we highlight the pressing livelihood and welfare challenges caused by recurrent geological hazards. Subsequently, we underscore the urgency and feasibility of establishing a comprehensive geological monitoring platform in coastal cities to address these challenges. We then elaborate on a three-phase deployment strategy for this early geological hazard monitoring platform, demonstrating its practical application. Furthermore, we identify two critical scientific issues requiring immediate attention: (1) the tectonic evolution mechanism of Sri Lanka, and (2) the stability of shallow geological structures in coastal cities. To this end, we emphasize the necessity of utilizing the latest seismic data to focus on studies of geological and velocity structures in Sri Lanka's coastal areas. Establishing standards for geological stability assessment and analyzing the temporal and spatial variation characteristics of geological hazards will provide scientific evidence for effective hazard prevention. More importantly, a more comprehensive model of geological structure evolution will be built through multidisciplinary approaches, integrating petrology, geochemistry, geophysics, and geological dating. This research aligns with the Belt and Road Initiative by prioritizing geological hazard prevention and advancing fundamental research on geological structures, carrying profound scientific and strategic implications.

Key words: geological hazards, geological hazards monitoring platform, tectonic evolution, shallow structure stability, Sri Lanka
