Study on Grouting Effect Evaluation of F4 Weathered Slot in Xiamen Xiang’an Submarine Tunnel
Abstract:
Measurement of water inflow from borehole, drilling and coring, ultrasonic inspection, ground-penetrating radar and field excavation are all used to test effect of grouting water shutoff and reinforcement in F4 weathered slot of Xiamen Xiang’an submarine tunnel. The five test ways are inter-validated to determine the grouting effect accurately and reasonably. It can provide a reliable basis for grouting design, construction and grouting effect test in similar strata. The application and development of grouting in submarine tunnel can be promoted.
