崩塌（危岩）是贵州地质灾害中主要灾种之一。本文利用重大地质灾害详细调查数据，研究发现贵州广泛分布的二叠系地层中，崩塌主要以倾倒式、规模为小型的地质灾害点为主；碳酸盐岩产生的崩塌众多，而溶蚀裂隙发育的栖霞组一茅口组中崩塌最发育。同时，崩塌点主要分布在贵州西北部及北部；就形成原因而言，作者认为卸荷裂隙与溶蚀裂隙的发育、陡峻的地貌形态、气侯条件和地震等都是造成崩塌发育的关键因子。

Collapse (unstable rocks) is one of the major geo - hazard in Guizhou Province. When analy- zing collapses in wildly distributed Permian strata in Guizhou, by using detailed survey data of major gco - hazards, it is found that rock collapses are mainly in gravity collapse at small scale; meanwhile, those collap- ses are more developed in carbonate rocks, especially in Qixia - Moukou groups whose dissolution fissures are developed. Moreover, the locations of collapses are mostly in the northwest and north of the province. As to the key factors causing collapse, the authors suggest that they are unloading fracture, dissolution fracture, steep landforms, climatic conditions and earthquakes.
