| 中文摘要:对黄土高原北部黄土坍窑灾害的调查和室内试验分析表明，在该区不断发生的坍窑灾害实际上是黄土边坡滑塌的一种表现形式，其分布与黄土颗粒成分变化的地带性密切相关，坍窑灾害的形成主要受黄土本身的物质组成、结构及力学性质控制。本文在实例剖析的基础上，分析了黄土坍窑灾害的形成机理，并提出了针对性的防治对策。 |

| The Mechanism of Cave Dwelling Collapse in Northern Loess Plateau |
|
|
| Abstract:Field investigations and in-door experiments indicate that the cavedwelling collapse in northern loess plateau is one of the forms of loess slumping hazards, whose distribution is closely associated with the particle constitution of the loess. The cave dwelling collapse is mainly attributed to the particle constitution, structure and mechanical properties of loess. On the basis of case analysis, the mechanism of the cave dwelling collapse and some correspondingengineering countermeasures are given in this paper. |
