摘　　要：本文围绕盾构衬砌管片的设计模型与压力荷载分布问题 ,首先概述了一种新的设计模型———梁 -接头不连续模型 ,在此基础上 ,利用管片内力的现场实测值 (如轴向力和弯矩 ) ,来反演确定作用在衬砌结构上的压力荷载的分布模式与大小 ,同时 ,运用反演分析技术对局部和全周地层弹簧作用模型进行了比较。A new design model for shield lining segments, beam-discontinuous joint model, is described in this paper. And based on the new model, the distribution mode and value of the loading pressure on the lining segments are back analyzed using the measured data of segment pieces such as axial force and bending moment etc. In addition, a partial-peripheral ground spring model is compared with a whole peripheral one in the backward analysis.
