By analysing the damage modes and their results of the computer system that would be faced with in wartime,strategies against these damage were introduced and a DSL solution was particularly recommended.

) involved in geo-stress level controlling the stability of surrounding rock,through triaxial test of red sandstone in Jurassic,the paper analyses on the deformation and failure characteristics of red sandstone under different conditions by triaxial loading and unloading,and reveals the damage modes and mechanical properties difference by different stress conditions.

According to the practical geological engineering condition and deformation failure characteristic of the dangerous rock body of Lianzi cliff, the 8 deformation failure modes and displacement equations are summarized.

By means of destroying method,paste carton was changed to folded carton after many tests.

Research on concrete's failure mode and prevention in Ningxia pickled area;

The stability and failure mode study on the tunnel-anchorage rock masses;

Researches on failure modes and fiber strain response of FRP-strengthened RC circular columns;

Re-research on single-direction compression experiment and damage forms of cast iron;

Through arranging the experimental data,the sample crack divergence situation and damage form were analyzed,it concluded that the damage form of the frame wall structure filled with masonry mainly represented flexible failure in small punch ration and shear-bending failure in large punch ration.
