A robust procedure of three-dimensional shape modeling for an objeci approximation is proposed A solid model isfirst prepared or reused for theprotovpe and then transfeerred to the model that approximates the shape of the object. Vertw geometv of the protoype is modified based on the multi-directional silhouettes and light stripe puttem projection. Topology of ihe mesh, shape and connectivilg/ of the vertices, of the protoppe is consewed throughout the modeling process. Stable meshing and accurate shape approximation are achieved, startingfrom a simpk or U dedicated model with desired meshes. A dedicated male sculpture and a simple cylinder with quadrilateral meshes are demonstruted f i r the shape approximation. This eliminates the hboriolrs modeling procedures, rewing a proven or simple and stable model, and the complicated camera calibrations.

The tensile creep test of the post-installed anchor was carried out by the improved spring type creep test equipment. The measurement of creep deformation from non-load and creep fracture time was possible over a long period of time by this equipment. The creep deformation at about 1/3 load of the maximum load increase slightly for the duration of 90 day, but the creep deformation is very small, and creep fracture will not occur in 50 years. And at 80% of the maximum load, creep fracture occurred in 168 days.
