仅几年,我设计院承接秦皇岛青龙满族自治县的公路项目较多,青龙县境内多山峦,沟壑纵横,从公路的测量、设计到工程施工放样各个环节都带来了不少困难,开山施工时开口线的放样就是其中之一,文章通过工程实践,总结了一套比较适用于深路堑路基开口线的测量方法,提高了测量速度和精度。 Only a few years, I Design Institute to undertake Qinhuangdao Qinglong Manchu Autonomous County highway project more, Qinglongxian mountainous, ravines aspect, from the measurement of the road to design lofting all aspects of construction have brought a lot of difficulties, the construction of mountains Open-line lofting is one of them. Through engineering practice, the article summarizes a set of measurement methods that are more suitable for the opening of deep-cut embankment and improves the measurement speed and accuracy.
