经过多年对整体式轨道的激烈讨论 ,终于尘埃落定。在下列情况下建议铺设整体式轨道 ,或加以劝阻 :(1)只要隧道穿过的岩层允许 ,在长度大约 5 0 0m的隧道中 ,原则上要铺设整体式轨道。在既有的隧道中改铺整体式轨道也是有意义的。其理由是 :捣固和拨道作业造成粉尘弥漫 ,加之作?
After years of intensive discussions on the orbit, finally the dust settles. It is recommended that an integrated track be laid or discouraged in the following cases: (1) Integral rails are to be laid in principle in tunnels of about 500 m in length, as long as the tunnel passes through. It is also significant to change the monolithic track in existing tunnels. The reason is: tamping and road work caused by dust filled, together with make?
