英语翻译
As the results that more precise tunnel internal cross section is determined as using the data obtained by ground laser scanning scheme in the tunnel and the cross section management system in the tunnel which is useful in the practical works is developed,the following conclusions are obtained.
First,as using ground laser scanner,3 dimensional data with the high accuracy could be promptly and exactly obtained and the random cross section at intervals of 0.1m,0.5m and 1.0m could be promptly determined as passing through the step of data treatment.
Second,as the results of analyzing the accuracy of dimensions by the number of measuring point for determining internal cross section,the laser scanning scheme appeared about 2.9% difference from the standard cross section dimensions,which meaned about 2.2% improvement of dimensional accuracy as compared with cross section dimensions determined by 15 measuring points.This,although there is the minute difference in a cross section,means that there is very big difference from the pre-existing quantity in considering the length of whole tunnel.Accordingly,it shows that the utilization of laser scanning scheme makes it possible to calculate more precise outbreak quantity and underbreak quantity as compared with the existing measuring methods.
Third,the cross section management system in the tunnel making it possible to calculate more precise outbreak quantity and underbreak quantity at the step of tunnel excavation and monitor them was developed.The developed GUI program makes more efficient and economical tunnel excavation management and monitoring possible and is judged to contribute to providing and utilizing the important foundation data for the maintenance and the management of tunnel as abstracting the data of random cross section in future.

作为结果,更精确的隧道内部横截面是决定采用获取的数据,地面激光扫描方案断面隧道和管理体系在隧道,适用于实际工作的开发,以下结论进行计算.
首先,当使用地面激光扫描,三维数据精度高,可迅速、准确地得到随机截面,每隔0.1m 1.0m亏损50万,可迅速决定通过数据处理的步伐.
第二,当结果的准确性分析度测点数目为确定内部截面、激光扫描方案2.9%出现在不同截面尺寸的标准,对meaned尺寸精度2.2%提高与截面尺寸取决于15测量分.这种事的,尽管有微小差异,意味着横截面上有很大的区别在考虑长度已经存在的数量整个隧道.因此,结果表明,利用激光扫描方案使得有可能爆发计算数量和取得更精确数量也相对于现有的测量方法.
第三,截面管理系统在隧道使它能够更精确计算数量和取得爆发的步伐的数量,在隧道开挖和监督他们出现了.发达GUI计划使得更高的效率和效益隧道开挖进行管理和监控可能的和被评为提供利用贡献的重要基础数据,为维护和管理的数据中提取隧道为随机截面的未来.
