THREE-DIMENSIONAL DEFORMATION PREDICTION METHOD USED FOR COMPUTERIZED CONSTRUCTION OF EXCAVATION EARTH-RETAINING WALL |
摘要 |
PROBLEM TO BE SOLVED: To provide a three-dimensional deformation prediction method used for computerized construction of an excavation earth-retaining wall, capable of three-dimensionally predicting deformation predicted according to the construction.SOLUTION: In a three-dimensional deformation prediction method used for computerized construction of an excavation earth-retaining wall: (a) deformation behavior of the earth-retaining wall at a present excavation time point is evaluated by using a three-dimensional measuring system; (b) an inverse analysis is performed by an elasto-plastic method for each of a plurality of measuring lines set in the extension direction of the earth-retaining wall, and the inverse analysis of a ground spring applying the deformation most suitable for displacement distribution of the present earth-retaining wall is performed at each measuring line; (c) estimation calculation at each excavation stage thereafter is performed by using the ground spring obtained by the (b) at each measuring line; and (d) estimation calculation results at all measuring lines are returned to the three-dimensional measuring system, and the deformation behavior of the earth-retaining wall at each excavation stage is three-dimensionally visualized. |
