AutoLISP在洞室开挖测量资料处理中的应用

Application of AutoLISP to Survey Data Processing in Cavern Excavating

水电站的洞室开挖,铁路、公路的交通遂道开挖,对超欠挖都有严格的控制指标,内业计算及成图都比较繁琐。为此,利用AutoLISP编程,实现了洞室超欠挖值及面积的计算,同时可实现断面图的绘制,并可在图上自动标注超欠挖值。实践证明,利用AutoLISP编程进行洞室开挖测量资料的处理可大大提高工作效率。

There is the strict control index to exceed underbreak value in cavern excavating of hydraulic power plant and the traffic tunnel excavating of railway and railway. This paper considers that the indoor calculation and map-making are fussy. With AutoLISP programming, the paper realizes the calculation of cavern exceed underbreak value and the area of cavern, meanwhile, realizes to annotate the exceed underbreak value on the map. Using AutoLISP programming, to process of survey information of cavern excavating, can raise greatly working efficiency.
