Paper Title:
Properties Test and Application on New Synchronous Grouting for the Earth Pressure Balance Shield
  Abstract

The type and performance indicators of the grout contribute great impact on the grouting effect. Uniform test method was adopted on the mix design optimization of the new grout, and the raw material requirements and performance requirements of the new grout were developed. Test results of the new grout, inert grout, and cement grout performances were compared and conclusions were drawn that the overall performances of the new grout were better than the other two type grouts. The modification of injection pump and pipe for the new grout injection were introduced, the preliminary application results of Shanghai and Suzhou metro showed that the new grout played a very good role on the surface subsidence control.
