中文摘要：

通过对集中荷载作用下弹性地基梁挠曲曲线函数进行积分，推出局部均布荷载作用下软土盾构隧道结构简化为弹性地基梁进行纵向结构分析时的挠度、转角、弯矩、剪力及地基反力的解析表达式，并对上海典型地质条件下的盾构隧道结构进行计算，得出其隧道结构纵向各个位置挠度、转角、弯距、剪力及地基反力的值。对局部均布荷载作用下软土盾构隧道结构纵向设计具有指导意义。

英文摘要：

The analytic solutions of the displacement, internal forces and ground reaction of the shield tunnel constructed in soft soil under locally uniformly distributed load was concluded by integration of the function of deflection curve of Winkler＇s elastic foundation under concentrated load. Those formulas were used to calculate the displacement, internal forces and ground reaction of Shanghai shield tunnel built in soft earth under some locally uniform load. The method to analyze the structure of shield tunnel is helpful to the longitudinal structure design of shield tunnel under any locally even load.
