摘　　要：为了解裂隙岩体内部水汽内循环(ICWV)特征规律,选择凤山采石场进行裂隙岩体温湿度监测,得到4个季节裂隙岩体非饱和带温湿度监测数据.对湿度数据进行横向及空间比对分析,结果表明,不同位置处的裂隙岩体非饱和带ICWV特征存在差异性,春季ICWV较为频繁,在孔深20~440cm均存在ICWV;夏季在岩体低处形成短时间的ICWV;秋季ICWV出现在岩体高处浅部;夏季和冬季在较高处,孔深20~100 cm ICWV频繁出现,并形成水汽的源汇项.春季在裂隙岩体内部形成湿度“异常分布区”,影响春季岩体ICWV规律.In order to obtain the characteristics of the internal circulation of water vapor(ICWV) in the fractured rock mass,so as to provide guidance and help for related research into the condensed water in there.The temperature and humidity of fractured rock mass in the Fengshan quarry were monitored,and the temperature and humidity monitoring data were obtained of the unsaturated zone of the four-season fractured rock mass.A horizontal and spatial comparison analysis of the humidity data showed that there were differences in the characteristics of ICWV in the unsaturated zone of fractured rock mass at different locations.In spring,the circulation was frequent,occurring in the hole depth of 20-440 cm;in summer,a short-term circulation was formed at the lower part of the rock mass and the autumn ICWV appeared in the shallow part.In summer and winter,it occurred frequently in the depth of 20-100 cm,and the source and sink of ICWV was formed.In spring,a humidity "abnormal distribution zone" was formed inside the fractured rock mass,affecting the circulation of ICWV in spring rock mass.
