| Abstract: | Because of the existence of the anchor bars, prestress,and surcharge in grillage supporting structure,the stress state within the slope is made very complicated.According to the similarity method and model test method,a indoor test was conducted and the soil pressure distribution in the grillage supporting structure with prestressed anchor bar in the loess slope was studied. The test results showed that the prestress and position of the anchor bar as well as the applying order of the prestress were the main factor influencing the stress state in the slope. |
