摘　　要：秦沈线山海关至锦州南段多为丘陵地区,路堑较多,路堑地段,部分地区出现弱场区现象。为使路堑地段弱场区的场强覆盖达到良好效果,增设了太阳能直放站。考虑到首次在铁路应用,为减少失误造成的危害,在保证工程工期的前提下采取先试验后推广的方式进行。在秦沈客运专线典型地点 K113～K115进行了试验。Most parts of Shanhaiguan-Jinzhou South section of Qin-Shen Passenger Line is located in hilly land area with many cuts,and part area of the cut sections is in feeble field conditions. The solar repeaters are added so that field strength coverage of feeble field becomes perfect in the cut sections.In order to reduce harms the fault would cause in case of its first application in railway,the mode is taken to carry out the test first and spread it later under the precondition of ensuring the time schedule of a project.The test is carried out in the typical place K113-K115 of Qin- Shen Passenger Line.
