隧道工程防水等级标准及检测

<地下工程防水技术规范>GB50108-2008将于2009年4月颁布执行.介绍了规范中防水等级标准的确定依据、修正原因、检测方法等,并进行了相关分析.提出了英国、德国铁路、隧道及地下工程的防水等级标准及借鉴内容,指出我国新修订的防水标准在湿迹、渗漏水量要求方面均有合理改进,说明了两种渗漏水量检测方法:在有流动水的隧道内设集水井和贮水堰进行积水量检测.并分析了湿迹与漏点的检测与换算.

Waterproof Grade Standard and Detection of Tunnel Engineering

GB50108-2008 technical code for waterproofing of underground works will be executed in April,2009. The determination basis,correction causes,detection methods of new waterproof grade standard are introduced and analyzed. The waterproof grade standard and the contents used for reference of British and German subway,tunnel and underground engineering are put forward,and it is pointed out that the new wet trace and leakage water requirements are reasonable than before. Furthermore,two kinds of detection method...
