シールドトンネル覆工作用土圧の逆解析について ON the Back Analysis of Earth Pressure for Shield Tunnel Lining
Shield tunnel lining is generally designed by assuming the patternized standard loads. But when a tunnel is to be designed under the unprecedented earth conditions or in the case of extremely large tunnel, it is important to ascertain the safty of the design by enough examinations and experiments. In such cases, the verification by the model analysis will be very useful.<BR>In the tunnel lining experiment using photelastic method, the results are usually obtained as the inside stress distribution of lining model.<BR>This paper shows the method of converting the experimental values to the load patterns which are used in the design. The weighted constants corresponding to the each patternized load are obtained by the least squares.
