Abstract

To mitigate or even avoid water inrush and collapses caused by tunnels crossing water-rich broken rock mass, a comprehensive advanced prediction system based on geological analysis, TSP (tunnel seismic prediction) method and advanced drilling is proposed. The unfavorable geology is evaluated through geological analysis, and then the TSP method is used to locate the unfavorable geological body in front. Subsequently, advanced drilling is used to predict the location and scale of the unfavorable geological structure after it is confirmed. Two engineering examples of the water-rich fractured segment of the Central Yunnan Water Diversion Project demonstrate that the proposed technology could accurately predict the location and scale of unfavorable geology and water inrush. Corresponding early warning measures and countermeasures can be made in time to reduce the probability of geological disasters such as mud inrush, water inrush, and landslides in the construction process and to ensure the safe construction of the tunnel.
