摘要:
为分析溶蚀与侵蚀对某间歇性运行供水隧洞安全运行的影响，采用现场调查、取样测试和无损探测等方法进行研究。结果表明：隧洞混凝土抗压强度与溶蚀呈显著负相关，隧洞脱空与侵蚀呈显著正相关；溶蚀部位混凝土强度降低，是导致隧洞混凝土抗压强度存在空间变异性的主要原因；目前溶蚀与侵蚀导致的混凝土强度损失与隧洞脱空尚不足以影响供水隧洞结构稳定，但随着溶蚀与侵蚀的进一步加剧，可能导致供水隧洞破坏。
Abstract:
Field investigation, sampling analysis and non-destructive detection were used to explore the effect of corrosion and erosion on intermittently operating water supply tunnel. The compressive strength of tunnel concrete was negatively correlated with corrosion, and cavity of the tunnel was positively correlated with erosion. The decrease of the concrete strength at the corrosion site was the main reason for spatial variability of concrete compressive strength in the tunnel. At present, the loss of concrete strength and tunnel voids caused by corrosion and erosion was not enough to affect the structural stability of water supply tunnel. However, water supply tunnels might be damaged with the aggravation of corrosion and erosion.
