贵州崩塌滑坡的特点及防治技术

The Characteristics of Collapses and Landslides and its Preventing Technologies in Guizhou of China

贵州省崩塌、滑坡具有明显的特点,对应的公路崩塌、滑坡防治方法应结合其特点.尽管滑坡防治技术在工程得到广泛应用,但滑坡防治方案的选型有许多问题需要进一步解决和完善.本文在参考有关文献的基础上,总结贵州省崩塌、滑坡的塑流—拉裂、弯曲—拉裂、蠕滑(滑移)—拉裂、滑移—弯曲和滑移—压致拉裂5种地质模式的特点及其实例分析,并结合公路建设和运营的实际情况,提出贵州省公路崩塌、滑坡的防治技术及目前需要解决的问题,力求为贵州公路勘察、设计、施工及运营管理等提供科学依据.

Geological hazards of collapses and landslides take place frequently in Guizhou Province, as severe disaster area of geological hazards in our country. It has obvious characteristics to collapses and landslides in Guizhou Province, and the preventing technologies should combine its characteristics. Though preventing technologies used widely in project, the selection of landslides preventing schemes has a lot of problems need solving and perfecting further, so, this subject becomes the difficult and hot point in the geotechnical engineering world of Guizhou Province. This text summarized the characteristics of five geological models and their examples of collapses and landslides in Guizhou Province of China on the basis of consulting relevant documents, these five geological models am plastic flowing and fracturing, bending and fracturing, creep or sliding and fracturing, sliding and bending and sliding and compression, and combining road construction and actual conditions of transportation, proposed preventing technologies and problems needed to be solved of collapses and landslides in the highway of Guizhou Province, made every efforts to offer scientific basis for the thing that operation management etc. in the highway of Guizhou Province. , designing, constructing and
