• 3 . under different kinds of wall rock and the same condition , from ii iii v kinds of wall rock , and conditions of construction period and operation period , it gradually increases that the maximum of displacement and the first main stress third main stress of pipe liner structure
  3 、不同种类围岩在相同的工况下，从、 、类围岩看，不论是施工期还是运行期，管片衬砌结构的位移的最大值和第一主应力、第三主应力最大值都逐渐增大。
• 1 . under the same kind of wall rock and the same condition , displacement of pipe liner is symmetry , for tunnel structure and suffered load are symmetry . as level terra stress is bigger , the maximum of displacement and the first main stress occur in tie - in of pipe liner structure , and its direction is radial and points in hole ; the direction of the third main stress is annular and its maximum occurs in top and bottom hole inner
  1 、同一类围岩在同一种工况下，由于结构和荷载的对称性，管片衬砌结构的位移也表现出对称性，因水平向地应力较大，位移最大值、第一主应力的最大值发生在管片衬砌结构的接头处，方向为径向指向洞内；第三主应力的方向为环向，较大值发生在洞顶和洞底内侧。
• 2 . under the same kind of wall rock and different conditions , the maximum of displacement and the third main stress of pipe liner structure in construction period is bigger than these of operation period , and the maximum of the first main stress of pipe liner structure in construction period is smaller than these of operation period
  2 、同一类围岩在不同工况下，施工期管片衬砌结构位移的最大值、第三主应力最大值比运行期要大，施工期的管片衬砌结构的第一主应力最大值比运行期要小。
