The traditional engineering animation is realized by building the model in 3D modeling software,and then by rendering to get serial frames to form a steam-media file.

An analytic study of stress and displacement during dynamic construction is conducted on the immerged underground tunnel.

Based on deep foundation excavation case,this paper introduces the application of monitor and dynamic construction technology in soft soil foundation pit with internal bracing system, and it has important meaning to restrict the strain, to improve the safety of the excavation and to protect the surrounding environment.

Based on the project of expressway tunnel in Zhejiang Province,the entire dynamic construction process of the tunnel is simulated by 3-dimention finite element method with MARC software.

Theoretical solution for consolidation of composite foundations considering construction disturbance and loading effect;

In this paper,on the basis of the previous researches,the concept of construction disturbance is discussed,and an expression of disturbance degree is set up and the calculation model against heave for the stability of deep excavation is established.

An attempt is made to express the degree of construction disturbance by the shear strain on the basis of the study of compression characteristics of soils influenced by different shear strains.
