泰安市岩溶塌陷形成的地质环境背景及其与影响因素的关系

Relationship between Geological Environment Background of Karst Collapse and Its Influencing Factors in Tai'an City

摘要:

泰安市岩溶塌陷集中分布在泰山火车站南侧以旧镇铁路三角区为中心的城区岩溶水源地、牟汶河畔的旧县岩溶水源地、东西羊娄村3个塌陷分布区。岩溶塌陷经历了发生→发展→高峰→衰减的历程。该文概述了泰安市岩溶塌陷发育历史与现状及其危害，形成的地质环境背景，阐述了岩溶塌陷与岩土体类型、地质构造、大气降水、人类对岩溶地下水开采活动等影响因素的关系。

Abstract:

Karstic collapses occurred in Tai'an city mainly distributed in three areas, they are district city water source as the center of Jiuzhen railway triangle area in south part of railway station, Jiuxian karst water source near Mouwen river, and east and west Yanglou village karst water source. In this paper, an overview of development history of karst collapse, present condition, harm and the formation of geological environment background of karst collapse in Tai'an city have been introduced. Relationship among the influencing factors of karst collapse, rock and soil types, geological structures, atmospheric precipitation and human activities to karst groundwater mining have been studied as well.
