Abstract Normal materials are difficult to satisfy the requirements of filling and grouting the water rich karst for subsequent shield tunneling，an environmentally friendly controllable paste grout(TGM) is thus developed. The main performance parameters of TGM material and the behavior of grout in underwater Karst were tested through laboratory test on large samples. The TGM materials were successfully applied to grout the underwater karst in the project of the river cross shield tunnel of Metro Line 3 in Changsha. The TGM material solidifies fast，increases fast in strength，has high fluidity，low rate of water desorption，low rate in volume contraction and rapid onset of early strength，moderate late strength. When the clay pulp accounts for 1.30，the ratio of water to solid additives 1∶1，the content of additives a is 1%，and the content of additive b is 0.15%，the main performance of TGM is the best. Karst water flow rate is lower than 1 m/s，the retention rate is above 75%. The karst water cured grout after 12 h of solidification has the compressive strength of up to 2 MPa，90 d compressive strength 8 MPa，permeability coefficient 10－7 cm/s and has a stable microstructure. The on-site grouting application shows that TGM material can effectively fill the water karst，the permeability coefficient is approaching 4.7×10－5 cm/s，the shield tunnels successfully.

Key words： tunnelling engineering cross river shield tunnel water rich karst grouting TGM material Changsha metro line 3
