摘 要: 介绍了湖北地区岩溶发育的分布区域和岩溶塌陷地质灾害的基本情况,分析并研究了湖北地区,特别是武汉市已发生的岩溶地面塌陷灾害案例,从理论上分析了产生岩溶塌陷的各种诱发因素,如水文因素、地表水作用、水库蓄水、抽取地下水、振动作用、荷载作用等,探讨了岩溶地面塌陷的2种主流成因机制:潜蚀论、真空吸蚀论。经过实地考察和参考以往研究可知:湖北地区包括武汉市在内的大部分岩溶地面塌陷的成因机制均为潜蚀型。在此研究基础上,结合湖北已经出现的一些典型岩溶塌陷问题提出了相应的防治措施与监测方法,并对岩溶塌陷评价系统的开发提出了一些看法和建议,为湖北地区未来的发展和规划提供评价依据。
关 键 词: 工程地质学;防治措施;综述;岩溶塌陷;诱发因素;监测方法

Abstract: This paper describes the distribution of karst in Hubei province, regional and karst collapse of geological disasters in the basic situation, analyze and study of the region, particularly in Wuhan city, Hubei province have taken place in case of karst land collapse hazard, from the theoretical analysis of formation of various karst collapse induced factors, such as hydrological factors, the role of surface water, reservoirs, water storage, groundwater pumping, vibration effects, and load function, to explore the karst land collapse causes two main mechanisms: potential erosion theory and theory of vacuum loss. Through field trips and reference to previous studies we can see: the genetic mechanism of corrosion of the majority of karst land collapse of Hubei province including Wuhan city is in latent type. Based on this study, combined with the emergence of some of Hubei, the paper puts forward a typical karst collapse in the corresponding control measures and monitoring methods, and makes some observations and recommendations on the development of karst collapse evaluation system for providing evaluation basis for the future development and planning of Hubei province.
Key words: engineering geology; control measure; review; karst collapse of ground soil; causative factor; monitoring methods
