摘要
以安庆市集贤关一处高陡岩质边坡为研究对象,结合裂隙岩体内春夏秋冬四季4 m深度范围内的温度与相对湿度监测数据,通过研究裂隙岩体内的水热运移和相对湿度过饱和频率的变化特征,对凝结水形成区域进行划分。结果表明:裂隙岩体内水汽过饱和频率沿水汽运移方向逐渐增加;夏季裂隙岩体内由浅到深依次为水汽欠饱和带、近饱和带、过饱和带,凝结水主要形成于深部,秋冬两季依次为水汽欠饱和带、过饱和带、近饱和带和欠饱和带,凝结水主要形成于浅部,春季依次为水汽欠饱和带、近饱和带和过饱和带,凝结水形成区域的分布范围较大。
Taking a high and steep rocky slope in Jixianguan,Anqing city as the research object,combining with the temperature and relative humidity monitoring data within a depth of 4 m in the spring,summer,autumn and winter of the fractured rock mass,we divided the formed region of condensed water by studying the water vapor and heat migration in the fractured rock mass and the changing characteristics of supersaturated frequency of relative humidity. The results showed that the frequency of water vapor supersaturation in fractured rock increased gradually along its migration direction. In summer,from shallow to deep,the fractured rock mass is in the order of water vapor unsaturated zone,near-saturated zone and supersaturated zone and condensate is mainly formed in the deep;in autumn and winter,from shallow to deep,there are unsaturated zones of water vapor,supersaturated zone,near-saturated zone and unsaturated zone and condensate is mainly formed in the shallow part;in spring,the water vapor undersaturated zone,near-saturated zone and supersaturated zone are in order and the distribution range of condensate formed region is large.
