摘要
G318线是通往西藏的咽喉要道,在天全县内全线为山岭重丘区二级公路。2014年9月24日,G318线天全段两路乡K2714+800m处发生塌方。论文以该处崩塌为例,对其地质条件进行了详细分析,阐述了边坡岩体特征、边坡形态雨水、风化、人类工程活动等内外力的综合影响是崩塌产生的原因;并运用Rockfall软件对其运动速度和运动轨迹进行了模拟分析,在此基础上提出了"主动防护"的防治措施。
The G318 line is an important road to Tibet,in Tianquan County in line for mountainous area highway two.In September 24,2014,the Road collapse occurred Tianquan line of two Xiang K2714＋800m.In this paper,the landslide as an example,the geological conditions are analyzed in detail,describes the comprehensive influence of rock slope characteristics,the slope shape rain and weathering,human engineering activities and the external force is the reason of collapse.And the use of rockfall software on its movement speed and trajectory of the simulation analysis,on the basis of the ＂active protection＂ of the prevention and control measures.
