一、我国公路建设的快速发展对公路工程检测仪器提出了新的需求我国现有公路96万公里左右,平均每万平方公里国土仅有1千公里公路,与美、英、法、西德甚至印度差距较大。我国公路不仅里程少,而且等级低,现有公路中尚未达到国家技术等级的占39%;一、二级公路只占2.89%。我国公路的这种状况已成了制约国民经济发展的重要因素之一。随着我国经济建设的调整和改革,公路运输得到了应有的重视。加速公路建设、改善运输结构、促进运输现代化和各种运输方
First, the rapid development of highway construction in our country put forward new demands on highway engineering detection instruments. There are about 960,000 km of existing highways in our country and an average of only 1,000 km of roads per 10,000 square kilometers of land. Compared with the United States, Britain, France, West Germany and even India is far behind. Our country highway not only has few mileage, but also has low rank, and 39% of the existing highways have not yet reached the national technical level; only 1.89% of the first and second grade roads. This situation of our country’s highways has become one of the important factors that restrict the development of the national economy. With the readjustment and reform of China’s economic construction, road transport has received due attention. Accelerate highway construction, improve transport structure, promote transport modernization and various transportations
