| Abstract: | Shield surroundings of been analysised, tunneling is a major construction method to cross rivers. The special Xiangjiang River tunnel whose shield is a crossed in Nanhu Road have which includes karst caves, ＂red strata＂ with the features of weak dia- genetic process, suspcetible to be softened and can be easily disingtegrated,high content of Quartz and gravel and ＂upper-soft and lower-hard＂ stratum with small thickess of covering. After risks are analyzed for shield tunnel construction under these complex geological conditions, some measurments are put forward. The study can provide an in- structional reference to both design and construcation of the Changsha Xiangjiang tunnel at Nanhu Road. |
