    • PROBLEM TO BE SOLVED: To provide an optimum arrangement selection method of a measuring apparatus in measurement of an earth retaining wall in excavation work, capable of achieving suitable measuring apparatus arrangement.SOLUTION: Before starting excavation work, design calculation of an excavation earth retaining wall on a representative cross section is performed to construct a function z=g(y) of depth and displacement (step S1). A distribution shape in an extension direction of the displacement on an earth retaining head position is set to z=h(x) (step S2). Three-dimensional deformation behavior of the earth retaining wall is set to z=f(x, y)=h(x)g(y) (step S3). Sorts (a displacement meter, an inclinometer)/number of measuring instruments and installation available positions are set (step S4). Arrangement corresponding to the number of measuring apparatuses is extracted at random by Monte Carlo simulation and the deformation behavior of the earth retaining wall is reproduced by a tertiary B-spline method (step S5). Accuracy improvement quantity in each arrangement is evaluated (step S6). While comparing optimum arrangements, the optimum arrangement of measuring apparatuses in the whole excavation work is determined.
