| 摘 要： | 岩溶塌陷的形成与隐伏岩溶区特定的地质环境条件密切相关。不同地区或同一地区不同地段，地质结构、水文地质条件的差异对松散盖层中土洞的形成时间、规模、形态等均起着明显的主导作用。因此，充分研究塌陷的形成条件是客观评价其易发性的基础。文章通过对泰安市主要隐伏灰岩富水区地质结构、盖层岩性组成、性状及岩溶发育程度的分析研究，以地质背景条件中的相对不变因素为依据，采用综合指数法对本区隐伏岩溶区岩溶塌陷易发程度进行了预测评价。旨在探索适宜的评价方法，以期为岩溶塌陷防治提供决策依据。

| Abstract: | The formation of karst collapse correlates closely to typical geo-environment in the covered karst region,and the difference of geological structure and hydrological condition in the different regions or different sections of the same region plays an important role in the formation age,scale and configuration of soil holes in loose cover.Therefore the study on the karst collapse formation condition is the base of susceptibility evaluation.Based on the analysis of the geological structure,loose cover property and karst development,the paper evaluates the karst collapse susceptible degree in the covered karst region using the synthetic index method according to the relatively unchanged factors in the geological conditions in order to develope the feasible evaluation method and basis for the collapse control. |
