| 摘 要： | 从穿越瑞士列奇堡隧道的挤压变形性极强的碳质页岩带的经验中,可以得出下述结论：圆形含承压单元的支护截面,其收敛变形性总趋势要比马蹄形不含承压单元的支护截面小；圆形支护截面与马蹄形支护截面的变形性没有本质的区别；由于山体构造的不均一性,导致开挖断面的不规则变形,这是使承压单元过早脱落的原因。

| Abstract: | The experiences with the driving of the Letschberg-Basis tunnel through the carbonaceous shale can be summarized as follows:The convergences of the circular profile with yielding elements tend to be smaller than with the horse-shoe profile without such elements.The horse-shoe profile and the circular profile do not differ signifi- cantly in ductility.Irregular deformations of the mined cross section due to inhomogeneities of the rock mass led to the premature loss of yielding elements. |
