The upper soft and the lower hard adverse geolog-ical exist great risk of construction during the construction of metro shield. In this article, the author takes the Shenzhen Metro 2227 standard as an example to give an account of the choice of ground reinforcement location, reinforcement proc-ess and pipeline protection etc. Making sure that the shield sm-ooth opening after reaches the stop position, and the continuity of the shield tunneling to reduce the risk of construction.
