The aim of Subproject A4 is a constitutive model for the support medium of Earth-Pressure-Shields based on rheological experiments. The scale of the experiments is widened to real-scale and the investigated types of ground will include the whole field of application of this type of machine including rock. Further, a new experiment to determine the workability of the muck will be developed so that even cohesive and extremely coarse ground can be tested. Further goals are the extension of the application range of EPB shields by conditioning with a new artificial soil and experiments to support the numerical simulations of the muck transport inside the excavation chamber in Subproject C4.

子项目A4的目标是基于流变实验的土压盾构支撑介质的本构模型。实验规模扩大到真实规模，所研究的地面类型将包括该类型机器的整个应用领域，包括岩石。此外，将开发一种新的实验来确定淤泥的可加工性，以便即使是粘性和非常粗糙的地面也可以进行测试。进一步的目标是扩大土压平衡盾构的应用范围，通过调节新的人造土壤和实验，以支持子项目C4中开挖室内的渣土运输的数值模拟。
