为研究武汉地区岩溶地质灾害成因及其防治措施，结合碳酸盐岩的平面与剖面分布规律，提出了武汉地区碳酸盐岩“六带五型”的概念。在平面上，武汉地区存在6个走向NWW-SEE的碳酸盐岩条带；在剖面上，根据碳酸盐岩上覆盖层的工程地质性能差异，划分出5种不同的地质结构类型。以碳酸盐岩“六带五型”为基础，碳酸盐岩展布区可划分为高、中、低3个危险性区。各危险区内，岩溶地质灾害防治原则不同。高危险区是岩溶地质灾害防治的重点，防治的基本原则是阻止上覆粉细砂的流失；中等危险区的防治原则是保护中部老黏土层或红层的完整性；低危险区应注意远城区老黏土中土/岩界面处土洞存在的可能性。各危险区应以地质结构为基础，在防治原则的指导下，制定相应的防治措施。

In order to study the causes and prevention measures of karst geological disaster in Wuhan, based on the plane and profile distribution of carbonate rocks, the author put forward the concept of“Six Belts and Five Types”(SBFT). Based on SBFT, the region of carbonate can be divided into 3 risk areas, namely the high, middle and low risk area. The prevention principle of karst geological disaster is different in each risk area. High risk areas are the focus of karst geological disaster prevention;it is the basic prin-ciple to stop the overlying sand erosion. The prevention and control principle of the middle risk areas is to protect the integrity of the old clay or red layer. In low risk area,we should pay attention to soil caves lo-cating to the interface between old clay and rock in the outer suburbs. It should be under the guidance of the prevention principle and based on its karst geological section to formulate corresponding prevention mea-sures for each risk area.
