摘要(Abstract):

本文根据一隧洞施工现场的实测爆振波特性,就爆振波对隧洞衬砌的浇筑时间、衬砌混凝土受振后的强度降低问题进行了室内爆振模拟试验,并应用损伤力学理论对试验结果作出了合理解释;对工程上所关心的安全爆速、衬砌的安全距离及合理衬砌时间等重要参数都给出了明确解答。
Based on characteristics of blast waves measured on the construction site of a tunnel, a blasting simulation test on the effect of blasting wave on concreting time and strength of concrete lining has been carried out in the labolatory.A reasonable interpretation on test results is given with the damage mechanics theory. And some important parameters, such as the safe blasting velocity ,safe lining distance time for tunnels in blasting engineering are definitely explained.
