摘要
本文对三种岩溶塌陷形态─—塌井、地面下沉和地面裂缝的产生条件进行了分析。为解释直径很大的塌井，提出“组合塌井”概念。地面下沉可理解成土体下沉量很小而直径特大的“组合塌井”．而地面裂缝则是地面下沉的伴生产物。
The conditions under which form three shapes of karstic collapse,i.e.collapse well,landsubsidence and surface cracks,have been analysed in the paper.For explanation of the col-lapse well with large calibre,a concept of combined collapse well is presented.Land subsidence may be considered as the combined collapse well with large calibre andsmall stibsidence,and surface cracks are the byprodtict of land subsidence.
