CALCULATION METHOD FOR IMPROVEMENT DIAMETER OF GROUND IMPROVEMENT BODY
To easily calculate the improvement diameter of a ground improvement body.SOLUTION: In a calculation method for an improvement diameter D of a cylindrical ground improvement body 100 created by injecting cement milk CM into the ground G by using a high-pressure injection agitation method, a sample is taken from the ground improvement body 100 created in the ground G whose water content and saturated unit volume weight have been investigated and whose ejected mass of cement milk CM per unit length of the improvement length has been determined, the calcium content of the sample is measured, and the mass proportion of soil particles 110 that make up the ground G in the sample is calculated to calculate the improvement diameter D of the ground improvement body 100.SELECTED DRAWING: Figure 2
【課題】容易に地盤改良体の改良径を算出する。【解決手段】高圧噴射撹拌工法によって、セメントミルクＣＭを地盤Ｇ内に噴射して造成した円柱状の地盤改良体１００の改良径Ｄの算出方法であって、含水比及び飽和単位体積重量が調査された地盤Ｇ内に造成され改良長の単位長さ当たりのセメントミルクＣＭの噴出質量が求められた地盤改良体１００からサンプルを採取し、サンプルのカルシウム成分を測定し、地盤Ｇを構成する土粒子１１０のサンプル中の質量割合を算定して地盤改良体１００の改良径Ｄを算出する。【選択図】図２
