盾构机穿越花岗岩球状风化体时掘进参数的控制分析

Control analysis of shield tunneling parameters when through the granite globular weathering body

本文以深圳地铁5号线民治站～五和站盾构区间为工程实例,分析地铁盾构施工时盾构机掘进参数的变化情况,并对这些掘进参数进行分析,得到盾构机穿越花岗岩球状风化体时掘进参数的变化范围。希望对类似工程的施工具有一定的借鉴作用。

As Shenzhen metro line 5 from the people--administer station to five co--station for example, the changes of shield tunneling parameters has been analyzed when shield constructs in metro. Statistical analysis also has been done for these tunneling parameters. The variation range of tunneling parameters has been got when shield through the granite globular weathering body, which have a certain reference for the construction of similar projects.
