摘要
《岩土工程勘察规范》(GB5 0 0 2 1- 2 0 0 1)在水 ,土对混凝土腐蚀评价中 ,取消了过去有关隧洞、竖井、水坝为Ⅰ类环境的规定。针对对隧洞、竖井工程如何评价地下水腐蚀的问题 ,该文以工程实例说明地下水对隧洞、竖井腐蚀的物理特性和化学特性 ,并指出了按规范评价的方法要点。
For the evaluation of concrete from water and soil in the 《Code for Geotechnical Engineering Investigation》 (GB50021-2001),the former stipulation about the tunnel, shaft and dam site environment being classified as category I has been canceled. Aiming at the problem of how to evaluate the corrosion from groundwater to tunnel and shaft engineering, in the paper, the physical and mechanical characteristics of corrosion from groundwater to tunnel and shaft are illustrated by engineering examples, and the key points of evaluation according to the said code are presented.
