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,介绍了大半径竖道腰放样设计的计算步骤和方法。

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.

该方法无假定结构零几何,而可以一次得到对应于(即预应力)几何的结构施工放样尺寸(即零几何),并通过分级加载对该方法的精度进行了检验。
