边坡的失稳受到降雨、植被等因素的影响。以2010年海南吊罗山滑坡实例为研究对象,从气候和植被的角度出发,考虑雨水渗流和植被破坏的影响;通过数值计算和三轴试验,分析了吊罗山滑坡的诱发原因及影响机理。研究发现:吊罗山湿热交替气候的降雨蒸发作用使红粘土出现缩胀性裂缝,以及山坡原有热带雨林被破坏后改种槟榔树,是滑坡发生的两个主要原因。
Slope instability is affected by rainfall, vegetation and other factors. Taking the case of Diaoluoshan landslide in Hainan Province in 2010 as the research object, the influences of rainfall seepage and vegetation damage are considered from the perspectives of climate and vegetation. The causes and influencing mechanisms of the Diaoluoshan landslide are analyzed by numerical calculation and triaxial tests . It is found that the main causes of landslides are the rainfall-evaporating action of the Diaolu Mountain alternate climate, which causes the shrinkage of the red clay and the replanting of areca trees after the original tropical rain forest was destroyed.
