| 摘 要： | 通过对自行走式隧道掘进机在地下爬坡过程中引起的地表变形进行了研究，结果表明：掘进机行进轨迹的纵向沉降曲线与随机介质理论预计的沉降曲线接近；在自行走掘进机埋深较浅时，横断面沉降曲线与Peck理论正态分布曲线误差较大，周向增阻结构嵌入土体能够造成地表土体的隆起。

| Abstract: | Through studies on the ground surface deformation that the self-walking TBM drills in the ground by climb- ing. The relevant results show that., the longitudinal settling tank curve over the self-walking TBM track is similar with the set- tling tank curve that the stochastic medium theory predicts; There is a large deviation between the transverse settling tank curve being formed when self-walking TBM is covered shallowly and the theory of normal distribution; the earth＇s surface soil is de- formation being embedded of the ring resistance structure on some degree. |
