摘　　要：为探索裂隙岩体内凝结水的时空分布规律,以宜阳锦屏山为研究区,监测夏冬两季研究区不同方位裂隙岩体内不同孔深位置处的空气温湿度数据,并分析其绝对湿度与相对湿度。监测数据显示相对湿度多时段连续达到饱和状态。时间上,夏、冬两季各壁面裂隙岩体内均有凝结水形成,夏季比冬季更易形成凝结水,冬季夜晚较白天更易形成凝结水;空间上,研究区裂隙岩体内凝结水分布情况受温度、水分分布及运移传递规律影响,除东、南两壁受冬季西北风的影响,壁面高位置处受太阳辐射较强,部分汽态水向低位置处运移,使得高处凝结水分布范围比低处小。夏季岩体内部凝结水区域外边界在孔深20~50 cm,冬季约在100~200 cm。The distribution of condensate water in fractured rock mass can be used in many fields,such as agriculture,forestry,civil engineering and environment.In order to explore the temporal and spatial distribution of condensate water in fractured rock mass,temperature and humidity at different depths in different positions of fractures in the Jinping Mountain of Yiyang County are monitored in summer and winter.The absolute humidity and relative humidity are analyzed.The monitoring data show that the relative humidity reaches the saturation state for more than a period of time.In time,the condensate water occurs in both the summer and winter.It is more likely to produce condensate water in summer and in the night time in winter.In space,the distribution of condensate water in the fractured rocks in the study area is affected by the distribution and migration of temperature and moisture.In addition to the eastern and southern walls affected by the northwestern wind in winter,the solar radiation of the high position of the wall is so stronger that some of the vapor water moving to the low position,which makes the distribution of condensate water at the height higher than the low position.The boundary of the condensate water area in summer is around 20~50 cm deep in the hole and about 100~200 cm in winter.
