沈阳地铁隧道开挖蠕变效应
Creep effect of excavation of SHENYANG metro tunnel
摘要
Abstract
By the FLAC, a creep effect simulation of tunnel excavation of Shenyang metro No. 1 line was conducted and its long stability was analyzed. It can provide benefic references for long running of SHENYANG metro tunnel. The results shows: As the displacement distribution around the point of view after 10 years, the creep effect of the vault, followed by the order of the arch wall → Floor → waist, is the maximum.The crown should be the focus of long-term creep analysis also confirmed that surface creep change the conclusions of the largest effect. It is reflected that the deformation characteristics of underground shallow tunnels. From the analysis of the displacement - time and displacement rate - time curves, it is obtained the conclusion of stable creep tunnel. It is forecasted that the operations of subway tunnel will be in the long-term stability in the future. The results are important references and can be put into operation for the subway project in Shenyang.关键词
