Abstract: Combined with mechanical characteristics of open-hole eco-composite wall in horizontal and vertical loads and based on the shear resistance mechanism theory，the holed walls shear resistance mechanism system in simit state was set up． Through the numerical analysis of extension，inclined section shear bearing capacity calculation formula of the open-hole wall was deduced，and determined the reasonable value of the holed wall oblique compression bar effective strength coefficient． Test research，theoretical analysis and numerical simulation show that the proposed holed eco-composite wall inclined section shear bearing capacity calculation formula has the certain theory basis and practical value，which can meet the need of actual engineering calculation．
