Focusing on the reuse of tunnel muck, this study aims to prepare tunnel muck from the Suzhou Metro Line 8 into a synchronous grouting material that satisfies the engineering requirements of different geological conditions by adjusting the solidification material compositions through laboratory experiments. In this project, a new doubleline shield tunnel of Metro Line 8 intersects the existing doubleline tunnel of Line 3 at Tangzhuang Station, forming a unique layout with two layers of four tracks. The muckproduced grout used in this project has a consistency value of 113 mm, and the 7and 28day strengths exceed 1 and 2.5 MPa, respectively, satisfying the engineering specifications. The deformation monitoring data show that the muckproduced grout effectively controls the impact of the upper tunnel construction on existing structures. Utilizing shield tunneling muck to prepare synchronous grouting slurry can achieve resource utilization of muck while promoting green construction and reducing construction costs by approximately 750 thousand Yuan per kilometer (double line).
