铁路隧道的建设正处于前所未有的大发展时期,笔者在总结大量工程成功经验和失败教训的基础上提出了铁路隧道建设的基本理念:隧道必须建成遗产工程;隧道必须进行科学的风险评估;隧道建设必须合理工期、合理造价、合理合同、合理施工方案和设计原则;隧道必须进行信息化施工。提出了单双线隧道选择、隧道纵坡及辅助导洞设置、支护结构设计以及快速施工等隧道设计原则。隧道建设的理念和设计原则可指导今后铁路隧道的规划、设计和施工。
Damage on lining concrete in highway tunnels under combined sulfate and chloride attack

The combined effect from sulfate and chloride is one of the important reasons to cause the damage of lining concrete in highway tunnels. To investigate the effect of chloride ions on the corrosion of lining concretes under sulfate attack, ultrasonic detecting, compression test and X-ray Diffraction (XRD) were performed on the concretes to obtain the ultrasonic velocity, corrosion thickness, compression strength and corrosion products. The ultrasonic results, compression strength and XRD patterns confirmed that the existence of chloride certainly depressed the corrosion damage on the lining concretes under sulfate attack, and the depressing effect increased with the content of chloride in the composite solution. The corrosion damage on the concretes experienced three stages independent of the composition of corrosive solution: initial slower enhancement on the strength, stabilization period and linear degradation period. The existence of chloride mainly affected the final degradation stage and obviously decreased the corrosion thickness.
