重庆某高速公路危岩崩塌变形特征及治理措施OACSTPCD
Deformation characteristics and treatment measures of dangerous rock collapse in an expressway in Chongqing
文章以沪蓉高速公路K1515处五处危岩崩塌为研究对象,通过勘察、统计和分析查明了危岩崩塌区的工程地质条件和发育变形特征.研究结果表明:(1)W1、W2危岩体破坏模式为错断和拉裂式,W3-1危岩体破坏模式为倾倒式,W3-2危岩体破坏模式为滑移式,W4和W5危岩体破坏模式为鼓胀式;(2)W1、W2发生拉裂式破坏的稳定性系数分别为1.12和1.61,处于基本稳定～稳定状态;在暴雨工况下W3-1发生倾倒式破坏的稳定系数为0.41,处于不稳定状态;W3-2…查看全部>>
In this paper,five dangerous rockfall collapses at K1515 of the Shanghai-Chengdu expressway are taken as the research object.Through investigation,statistics,and analysis,the engineering geological conditions and developmental deformation characteristics of the dangerous rockfall collapse area are clarified.The research results show that:(1)the failure modes of dangerous rock masses W1 and W2 are misbreaking and cracking,the destruction mode of W3-1 dangerou…查看全部>>
