摘　　要：盾构法施工目前已广泛应用于我国地铁及电力、热力等隧道施工中。盾构始发是盾构由工作井进入正常掘进的一个施工过程,是盾构施工全过程的一个关键环节。通常情况下地铁隧道盾构机为整体始发,但一般的电力、热力等隧道以及超过一定长度的地铁隧道区间依靠较小的施工竖井始发,由于盾构机及其后配套台车自身长度限制,其不能在始发前全部位于始发井内,从而必须进行分体始发。本文就输电工程电缆隧道盾构施工分体始发的方式做了论述。Shield tunneling method has been widely used in the construction of subway, electric power, heat and so on.Shield is a key link in the whole process of shield construction, which is a key link in the whole process of shield construction,which is a construction process of shield tunneling from working well.Normally the subway tunnel shield machine for the whole of origin, but the general electric power, heating power tunnel and over a certain length of the subway tunnel construction on the smaller shaft departure interval, the shield machine and its supporting trolley length limit, not in before sending all located in the originating wells ,which must be carried out in separate launching.In this paper,the construction method of shield construction of cable tunnel in power transmission project is discussed in this paper.
