| 英文摘要 | Yielding support is often used in the squeezing tunnel to prevent damage to the lining induced by large deformation of the surrounding rock. Highly Deformable Elements (HDE) which is often installed along the circumferential direction of the shotcrete lining is a common type of yielding support. To determine the yield parameters of HDE, the support characteristic of the lining using HDE and the ground pressure considering strain-softening of soft rock were analyzed by an analytical method. The analytical solution showed that when considering the strain-softening of squeezing ground, the ground pressure has a non-zero minimum value. The minimum value of ground stress can be used to determine the constant yield stress of the HDE, and the corresponding deformation of the minimum ground pressure can be used to determine the deformation capacity of the HDE. Based on the variation in the design constant yield stress and yield displacement of HDE with the in-situ stress and the mechanical parameters of the soft rock, equations were proposed for determining of the yield parameters of the HDE. |
