谨防京郊平原发生深层隐伏岩溶塌陷

Beware of deep covered karst collapse in Beijing Suburbs Plain

文章从北京郊区平原之下隐伏基岩的岩性、构造及其水文地质条件出发 ,指出 :①京郊平原深部存在隐伏岩溶塌陷问题 ;②京郊平原开采深部基岩岩溶水与保护地质环境问题。文中不仅列举了国内外类似的实例作为佐证 ,还特别介绍了 1995年 5月 5日发生在京郊平原的首例大型深层隐伏岩溶塌陷。并对此进行了分析研究 ,指出了将来可能的发生趋势及其危险区。最后 ,建议有关部门尽早做好防灾减灾工作 。

Based on the lithology, structure and hydrogeological condition of buried bedrock in Beijing Suburbs Plain, the author thinks there are two problems in these areas. The one is covered karst collapse, the other is the relationship between mining karst water in deep bedrock and protecting geological environment. This paper presents the first large deep covered karst collapse occurring on 5th May,1995 in Beijing Suburbs Plain. Through analysis of this example, the tendency and dangerous region of karst collapse have been pointed out. In the end, suggest to arrange the work of controlling and decreasing geological hazards the earlier the better in order to protect the geological environment of Beijing.
