<P>PROBLEM TO BE SOLVED: To easily set the optimum rigidity of a displacement control material for controlling and inhibiting the settlement or horizontal deformation of a weak ground. <P>SOLUTION: A relationship between an area improving rate (a) as the ratio of the installation area of the displacement control material to the area of an original ground and a ratio Ep/Es of rigidity Ep of the displacement control material (a settlement control pile) to rigidity Es of the original ground is previously analyzed and found using the allowable displacement amount (a normalized settlement amount B) of the original ground, as a parameter, after installing the displacement control material. Based on the ratios, the optimum rigidity of the displacement control material is set for every area improvement rate. The allowable settlement amount of the original ground after installing the settlement control pile as the displacement control material is set, based on the normalized settlement amount as an index normalized with reference to the settlement amount when maximizing the rigidity of the settlement control pile. The optimum rigidity of the settlement control pile is set using a predetermined regression formula and chart. <P>COPYRIGHT: (C)2012,JPO&INPIT |
