| Abstract: | The paper introduces in detail the pre-reinforcement technology and the technical points of Wuhan rail transit Line 2, contracted to build by China Railway 13^th Bureau Group Corporation, when Xunlimen station crosses the existent light rail pier foundation. The real-time monitoring carried out during the construction process indicates that the distortion control of the adjoining foundation caused by the construction of crossing hyper-thick sand layers satisfies the design requirements and guarantees the operation security of the adjoining light rail. |
