There are more than twenty halls in front of cave in Mogao Grottoes,such as caves No.130,108,100,98,96,95,85,76,74,72,61,55,467,53,46,45,44,39,38,35,30-27,33-21,Most of caves have its own eaves building.The two kinds of architecture are both timber construction.After carefully research,we find that these special architecture were built during early Tang dynasty at the first time,developed in Middle Tang,and very popular during the period of Gui-Yi-Jun,and still continued in the West Xia and Yuan Dynasty.In this paper,the author specially discusses the two halls in front of caves No.130 and No.96.

在高建筑物(大桥的高塔柱,摩天大楼等)的施工放样过程中,在同一铅垂线上的建筑物特征点的平面坐标,随着建筑物的升高而改变,对此,测量员是否应事先按照不同高程计算出这些点的平面坐标再进行放样?曾经是引起争论的问题(例如在润扬大桥等桥梁的塔柱施工放样中)。本文首先在理论上证明了,椭球面上任一点,在不同高程投影面上的高斯平面坐标,与椭球的平均曲率半径成正比。其次,以上述结论为根据,明确和肯定了现行的对于高建筑物的施工放样方法。
