中缅油气管道安顺—贵阳段地质灾害类型及其成因分析

为了弄清中缅油气管道安顺—贵阳段沿线地质灾害的情况,通过野外实地地质考察,获得了安顺—贵阳段地质灾害有关数据,共发现灾害点34处,其中崩塌17处、不稳定斜坡4处、滑坡3处、地面沉陷10处,且以崩塌和地面沉陷为主;通过对诱发地质灾害的各种因素(地貌、地形坡度、水-岩相互作用、地震活动以及人类工程活动)进行分析,初步认定管道沿线的地质灾害的成因机制其实质是水-岩作用。该研究可为后期该类地质灾害的防治提供依据。

China-Burma Oil and Gas Pipeline Anshun-Guiyang Geological Survey and the Causes of Disasters

In order to understand the geological hazards along Anshun-Guiyang section of China-Burma oil and gas pipeline,this paper obtains the data concerned through a comprehensive field survey of this section.Altogether 34 hazard points are found,including 17 collapses,4 unstable slopes,3 landslides and 10 ground subsidences,with collapses and subsidences being in dominance.By the analysis of various factors that induce geological hazards,the paper makes a primary conclusion that water-rock interaction is the major genesis for the geological hazards along this section.This study can provide the proof for the control of hazards in the later period.
