一、前言随着我国铁路运输业的迅速发展,运量不断地增长,行车密度、速度逐步提高和大型机车、重载列车的使用,虽然近几年来对线路上部建筑的改造和加强,使线路质量有所改善,但基床的翻浆冒浆病害仍然得不到控制和整治。每年耗费了巨大的人力、物力和财力。以前贯用的几种处理基床冒浆的方法,如加厚道碴、砂垫层、横向盲沟、基床土换填、做侧沟降低地下水位、基面用三合土、混凝土板封闭基面等等,随着大运量、大密度、高速、重载列车的急剧增长,上述几种方法大都也相继失效了。
I. Introduction With the rapid development of China’s railway transportation industry, the volume of traffic continues to grow, the traffic density and speed are gradually increasing, and the use of large-scale locomotives and heavy-haul trains is increasing. In recent years, the upper part of the line has been rebuilt and strengthened, The quality has been improved, however, but there is still no control and remediation of the soiling of pulp beds. Spent a huge annual human, material and financial resources. Previously used in several methods of treatment of basement muddy, such as thick ballast, sand cushion, horizontal blind ditch, bed soil fill, side ditches to reduce the groundwater level, the base surface with trigeminal, concrete panels closed Etc. With the rapid growth of large capacity, high density, high speed and heavy haul trains, most of the above mentioned methods have also failed in succession.
