摘要
近年来,随着钢纤维喷混凝土应用的日益推广,其有关的理论及试验研究也越来越深入,但从总的趋势来看,理论研究还是落后于钢纤维喷混凝土的实际应用。文章对钢纤维喷混凝土作为隧道衬砌的作用机理从试验研究、理论模型及实际应用几个方面进行了探讨,建立了塑性铰力学计算模型,并对实际隧道工程进行了计算。
For many years, the study on theory and experiment of steel fiber reinforced shotcrete ( SFRS) has been developed in depth with the increasing application of SFRS. However in a whole the theory research is far behind of practical application. In this paper the study on mechanical behavior of SFRS as tunnel lining is presented in terms of experiment, theory model and its application. Moreover plastic hinge model is established and the analysis on practical tunneling is carried out.
