| SI anchor means the soil improvement anchor. The ground for supporting anchor is improved by JSP, and as a result, SI anchor body has about 80cm in diameter. SI anchor shows high pullout resistance by the frictional force between anchor body and ground, and the bearing capacity of anchor body. Especially the frictional force increases very much with increasing diameter of anchor body improved by JBP. In this study, model and field tests are made to analyse the mechanism of pullout resistance of SI anchor. Through model tests for the SI anchor in air dried sandy ground, strain fields of ground around SI anchor surface are analysed by a photo analysis method using the latex membrane on the wall of soil tank. The results of field tests are analysed by the strains measured by 10 strain gages attached on the inner wall of specially designed PVC pipe embedded in anchor body, and the strains of anchor body are also measured in the model tests. |
