基于智能勘测的隧道横断面自动化分析技术

Automatic analysis technology of tunnel cross section based on intelligent survey

随着智能勘测技术的发展,传统的横断面数据人工处理和分析方法已无法满足智能勘测海量数据的需求。针对该现状,研究了基于智能勘测的隧道横断面数据自动化分析的技术,采用Python语言进行AutoCAD的二次程序开发,能够自动判别隧道明、暗洞衬砌结构类型,并进行浅埋工况、偏压情况以及明挖刷坡方案的自动化分析。自动化分析程序成功应用于长赣铁路吉安段,有效地降低了设计人员处理和分析数据的时间,满足新型智能勘测的海量数据处理需求。

With the development of intelligent survey technology,traditional methods through manual processing and analysis of cross-sectional data can no longer meet the requirements of massive data of intelligent survey.Aiming at this situation,this paper studyed the automatic analysis technology of tunnel cross section data based on intelligent survey.The secondary program of AutoCAD is developed by using Python language,which can automatically distinguish the condition types of opencutting or undennining method of tunnels,and automatically analyze the shallow buried conditions,the unsymmetrial loading conditions and the slope brushing scheme in open-cutting cross section.The automatic analysis program has been successfully applied in Ji'an section of Chang-Gan Railway,which effectively reduces the time for designers to process and analyze data so as to meets the demand of massive data processing of new intelligent survey.
