1 路基工程期刊所走的历程 多年来铁路运输实践中证明病害多发生在路基上,因为它是铁路主要结构工程,工程浩大,环境条件复杂,也是工务维修的重点,累计整治耗资巨大。根据铁道部1984年初检查资料统计,在71 338 km正线上存在路基问题81 082处,延长11 055 km。“八五”前四年,主要干线水害,中断行车772次。累计中断时间9 083小时,其中百分之八十以上发生在路基上 1 Subgrade Engineering Journals go through the course of many years of railway transport practice proved that the disease occurred in the embankment, because it is the main railway construction projects, vast projects, complex environmental conditions, but also the focus of maintenance of public works, the cumulative remediation costly. According to the inspection data of the Ministry of Railways in early 1984, there were 81 082 subgrade problems on the 71 338 km line, extending 11 055 km. In the first four years of the “Eighth Five-Year Plan”, major arterial traffics were disrupted and traffic was interrupted 772 times. The cumulative interruption time was 9 083 hours, of which over 80% occurred on the roadbed
