Study on the anti-explosion performance of steel partition and reinforced concrete cylinder in soil
To investigate the anti-blast performance of the steel plate-concrete cylinder structure in the soil under underground blast load,the multi-material fluid-structure coupling calculation method was used to reveal the propagation law of the shock wave in the soil medium,the dynamic response and damage mechanism of the steel-concrete cylinder structure were analyzed,the explosion model test was carried out,the earth pressure distribution near the cylinder and the deformation time history curve of the explosion surface were obtained,and the accuracy of the numerical simulation was verified.On this basis,compared with the anti-blast performance of the traditional reinforced concrete tube structure,the failure mode and damage degree of the two structural forms were evaluated.The results show that the impact resistance of the steel plate-concrete cylinder is better under the same steel consumption rate.
