| Abstract: | The foam agent is used to regulate the soil condition during earth pressure balance (EPB) shield excavating, how to estimate the effect of the foam agent technique is very important and there are still some unknowns. Based on studying the tunnel boring method and property of foamed soil, some methods and judgment criteria for evaluation of the properties and effectiveness of the foam are discussed and some suggestions are given for its application and selection. |
