摘要：

Geometric modeling of the geological layers in the Channel Tunnel area employed local variography and kriging for computing meaningful predictions and confidence intervals. The results were used to design the alignment of the tunnel, and tunneling was completed on March 28, 1991, 1 month ahead of the initial schedule. Data from 85 borehole pairs drilled during tunneling enable the geostatistical prediction to be compared with the reality, which is seldom possible. They fully validate the geostatistical approach.
