本文从新构造运动与岩溶发展简史、水文地质条件与岩溶水循环、岩溶发育条件与发育规律三方面对昆明新机场航站区的岩溶形态特征和发育规律进行了研究。结果表明,断块差异升降运动及相对平静期相间出现,决定了区内垂直岩溶发育,且具多层性;处于两大水系分水岭的地带,其水动力环境以小流量的差流(南部)和平流(北部)为主,决定了航站区如溶洞、溶隙等岩溶现象以小规模兼少量的中等规模为主,不具备产生大规模的厅堂式水平溶洞的水动力条件;场区虽属于岩溶中等发育区,但密集的溶缝、溶隙及中小溶洞组成的强溶蚀带较发育。
In this paper, the karst morphological characteristics and development regularities of Kunming New Airport Terminal Area are studied from the aspects of neotectonic movement and a brief history of karst development, hydrogeological conditions and karst water circulation, karst development conditions and development rules. The results show that the differential up-and-down motion of faulted blocks and the appearance of relative quiet periods determine the development of vertical karst in the area and are multi-layered. In the watershed of the two major aquifers, the hydrodynamic environment is characterized by small-flow differential flow (south part) Peace flow (north), which determines the terminal area such as karst caves, karst karst phenomena such as small and medium-sized mainly do not have to produce large-scale hall-type horizontal caves hydrodynamic conditions; although the field area Belong to the middle karst development area, but the intensive dissolution, dissolution and dissolution of small and medium-sized karst cave formed more strongly erosion zone.
