TRIGGERING AND PREVENTION OF LANDSLIDE DISASTERS TO CAVE DWELLINGS IN LOESS REGION OF CHINA

摘要

A cave dwelling is a special but long-standing style of dwelling which is constructed into or against loess physiognomy in north and north-west China. Currently in China over 40 million residents live in cave dwellings. However, landslide disasters to cave dwellings become more frequent and disastrous in loess regions. Numerous casualties and property damages were reported. Loess landslide disasters pose vast threats to residents in cave dwellings. To investigate triggering factors and preventing scenarios regarding loess landslide disasters to cave dwellings is a pressing research topic facing geotechnical engineers and related professionals. This state-of-the-art study is launched to address this issue. Work scope covers three aspects: geological requirements of constructing cave dwellings, prerequisites and triggering factors of landslide disasters, and preventing scenarios of loess landslides. Summarization of triggering factors and disaster prevention scenarios establish a platform mitigating landslide disasters to cave dwellings.
