To improve the deficiencies of prefabricated autoclaved lightweight aerated concrete(ALC)panel such as susceptibility to cracking and low load-bearing capacity,a textile-reinforced mortar-autoclaved lightweight aerated concrete(TRM-ALC)composite panel was developed in this *** group of reference ALC panels and five groups of TRM-ALC panels were fabricated and subjected to four-point flexural *** was applied on the tensile side of the ALC panels to create *** variable parameters were the plies of textile(one or two),type of textile(basalt or carbon),and whether the matrix(without textile)was applied on the compression side of *** results showed that a bonding only 8-mm-thick TRM layer on the surface of the ALC panel could increase the cracking load by 180%−520%.The flexural capacity of the TRM-ALC panel increased as the number of textile layers *** reinforcement of the matrix on the compressive side could further enhance the stiffness and ultimate loadbearing capacity of the TRM-ALC *** panels with basalt textile failed in flexural mode,with the rupture of fabric *** with carbon textile failed in shear mode due to the ultra-high tensile strength of *** addition,analytical models related to the different failure modes were presented to estimate the ultimate load-carrying capacity of the TRM-ALC panels.

随着我国城市化进程的不断加快,城市中人们出行方式的选择也越来越多样化,同时交通领域内部发展也逐渐细分,在满足不同人群出行需求的同时,也更好地串联起城市内部与周边,促进区域协调发展。交通工程建设是交通领域发展的前提,而交通工程的建设具有投资金额大、建设周期长、过程复杂等特点,其中安全质量问题则是交通工程建设过程中的关键。因此,监管部门如何更好地参与到交通工程建设中,如何更准确的发现交通工程建设过程中存在的安全隐患,集中力量整改问题消除隐患,这也是工程建设过程中监管部门需要着重研究的。
