1994年11月8日至11日,由中国公路隧道学会主持的第三届全国公路隧道学术交流大会在重庆隆重开幕。随着国民经济的发展,我国高等级公路已从沿海地区向西南西北山岭重丘区延伸,公路隧道规模越来越大。据不完全统计,我国已建成公路隧道350座,总里程约90公里。1公里长以上的有37座,其中一半以上是近年建成的。公路隧道建设之所以能取得这样大的成绩,与全国公路隧道界浓厚的学术风气,科研和工程密切结合的优良作风分不开。近期开通的成渝
From November 8 to November 11, 1994, the 3rd National Highway Tunnel Academic Exchange Conference hosted by China Highway Tunnel Society was held in Chongqing. With the development of the national economy, the high-grade highways in our country have extended from the coastal areas to the heavy hill areas in the mountains of Northwest, Southwest and Northwest China. The size of the highway tunnels is increasing. According to incomplete statistics, China has built 350 highway tunnels with a total mileage of about 90 kilometers. Over 1 km long and 37, of which more than half are built in recent years. The reason why the construction of highway tunnels can achieve such a great result is inseparable from the excellent style closely combined with the strong academic atmosphere, scientific research and engineering in the national road and tunnel community.
