怎样进行隧道漏水的检查、观测和分析？
参考答案：
隧道漏水首先可进行表面检查，根据不同的漏水程度，润湿、渗水、滴水、漏水及结冰等，在分格检查展示图上做好详细记录。除表面检查外，还应进行长期的观测。观察时要注意洞内及洞外，平时与雨季及排水沟中流水量的变化，测量漏水量的大小、持续时间及变化情况等，并详细记录分析，一般有下 * * 种情况：
⑴平时漏水渗水，雨时雨后都无变化或变化不大，水源都属于土壤中水。
⑵平时不漏不渗，雨时又漏又渗，水源大都属于地面水，推测山顶必有洞穴，裂纹或土壤透水，如雨后隔相当时间洞内才开始漏水，可以根据时间的长短，估计山上进水地点的距离或考虑地质情况，以便找寻进水处。
⑶平时渗水漏水，雨时大渗大漏，水源是属于土壤中水与地面水都有。
