A Jet-Grouted Wall in Mitigating Tunnelling Effects on Adjacent Structures

Technical measures, such as an underground partition wall, could serve as recourse to mitigate the ground movements induced by excavation. In this paper field monitoring and numerical analysis were used to examine the performance of an underground jet-grouted partition wall in mitigating the effects of shield tunnel construction on an existing pier of the Xin-Zhong Road viaduct in the Changsha Subway Line 1 project in China. The performance of the jet-grouted partition wall was calibrated by the reasonable agreement found between the observed field measurements and the numerical results. An underground jet-grouted-column partition wall was tested to serve as an effective measure in ground movement control given the need of tunnelling nearby piled structures.
