摘要
枣庄岩溶塌陷始发于1981年，是全国较早发生岩溶塌陷的地区之一。多年来，随着对地下水开采量的逐渐增加，岩溶塌陷随之加剧。塌陷主要分布在松散层较薄的第四系覆盖区，发生时间主要集中于枯水年份或年内枯水期和丰水期初。塌陷的产生与发展规模受溶洞、土层和水等多种因素的综合影响，但过量开采地下水导致地下水动力条件急剧改变或水位大幅度下降是造成塌陷形成的主导因素。
Zaozhuang city is one of the area in which karst collapse earlier occurred in China,and it first occurred in 1981. For many years,as the rising taking of underground water,the karst collapse has become more serious- It mainly spreads in the Quaternary system cover areas where the looser layers are thinner, underlying open karst caves and cracks are under the Quaternary system. The collapse mainly occurs in the low - water years or during the beginning of the dry season and rain season in a year. The formation and developing scales of the collapse are affected by rnany factors, such as karst caves , sola and water, etc. However,the taking of the underground water which causes the hydrodynamic conditions changed and the water level highly descended in a factor for the karst collapse.
