The Study of Super Element Cable Sun Xiao-yu 1, a , Wang Zhen-qing 1, b 1 College of Aerospace and Civil Engineering of Harbin Engineering University, Harbin, Heilongjiang, P.
The proposed model is firstly verified by a simple cable system with three fixed pulleys and then applied to two real engineering systems: tower crane system and lifting system with pulley spreader beams.
The verification results satisfy the static equilibrium and deformation compatibility conditions of the structural system and basic engineering principles.

ABAQUS can reflect the character of soil constitutive model, and able to perform the calculate effective stress, it has a powerful interface processing functions to simulate the release between soil and structure, the phenomenon such as slip, with process fill and excavation ability of the specific problems in geotechnical engineering, and can set up the initial stress state, which calculate the lattice type steel sheet pile wharf structure has a strong applicability. [1] The simplified model We use shape steel sheet pile model cylinder which height is 21 m, diameter is 17.00 m, thickness is 0.0136 m and 5 m depth, related material parameter of the model in Table 1.
So, in the actual engineering design process we can consider do strengthen processing at the corresponding position, in order to improve the overall strength and stability of the structure.
