With project instance, this paper introduced the calculation procedure and method about lofting and designing the tunnel stringcourse with sweeping matrix vertical curve.

结合工程实例,介绍了大半径竖曲巷道腰设计的计算步骤和法。

Without assuming the form of unstrained state,the form of unstrained state corresponding to that of pre-stressed state can be obtained through this method directly.

法无需假定结构零状态几何,而可以一次得到对应初状态(即预应力态)几何的结构施工尺寸(即零状态几何),并通过分级加载对法的精度进行了检验。
