<p>PROBLEM TO BE SOLVED: To provide an estimating method for the execution quantity for each soil, character by which boring work can be remarkably reduced by estimating the soil distribution condition in the ground by using the density distribution using gravity prospecting, data obtained by boring, and sampling data on investigation of the soil constitution by drilling. SOLUTION: An average density to a designated depth is graded by gravity prospecting to create a gravity prospecting contour map, the gravity prospecting contour map is divided by grids, and the grade of density is written in each grid of the grid-divided contour map to create a grid-divided grade map. According to the grid-divided grade map and boring data 20, the stratum data 18 is created. According to the stratum data 18, a stratus attribute model 22 where the soil appearing by each grid is expressed in three dimensions is created. An execution model 24 is created according to an execution plan, and an execution model 26 by soil attributes is created by the logical operation of the soil attribute model 22 and the execution model 24 to calculate the execution quantity for each soil attributes in the execution range.</p> |
