摘要:
就滑坡组成和发生机制,与《贵州关岭"6.28"特大滑坡特征和成因机理》一文作者进行商榷。笔者认为"超压密岩土边坡失稳理论"可以较好的解释大寨滑坡-碎屑流灾害的突然发生。"上硬下软"坡体结构,是大寨滑坡发生的地质基础;强降雨快速入渗,是导致岩层裂隙和大气突然贯通,负压立即消失,高陡坡体迅即失稳的诱因。
Abstract:
In this paper, the composition and formation mechanism of the Dazhai Landslides, Guanling, Guizhou Guizhou, occurring on 28th of June， 2010 is discussed with the article of“Guizhou Guanling Landslide Formation Mechanism and Its Characteristics”. The theory about“slope failure of overconsolidated clay” is satisfied to explain the sudden occurrence of the Dazhai LandslidesDebris flows Disaster. The special rock structure of the slope with the upper part of hard rocks and the lower part of soft rocks is the geological basis of the landslides. The quick and plenty infiltrattio0n of runoffs during the rare heavy storm event was the triggering factor of the disaster, which resulted in sudden coalescence of the cracks in the rocks, then air entered into the close cracks, the negative pressure immediately disappeared , consequently, the high and steep slope suddenly failed.
