Through uniaxial compression test of high titanium blast furnace slag（HTBFS） pervious concrete,it is found that the compressive strength of HTBFS pervious concrete can reach 9.2 MPa,which meets the design strength requirements of no-fines concrete on road base.And the morphology of failure surface for HTBFS pervious concrete with small particle size is mainly shown as aggregate fracture,slightly different from that of ordinary pervious concrete.In addition,through numerical simulation of uniaxial compression,the mesoscopic mechanical parameters of HTBFS pervious concrete were obtained,based on which the uniaxial compression numerical simulation curves can coincide well with the stress-strain curves of HTBFS pervious concrete with different particle size.Furthermore,the fracture development of HTBFS concrete model was observed by numerical simulation,and the feasibility for PFC simulation of uniaxial compression test of HTBFS pervious concrete was verified.The results of above research can provide reference for studying the stress state and failure mechanism of HTBFS pervious concrete.
