| Cost effective design and construction are necessary to establish the design concept of tunnel lining. Loosening load acting on the concrete lining is compared with Terzaghi tunnel theory and numerical analysis. It is analyzed under the condition of weathered rock and soil with varying in-situ stress ratio ($K_0$). Based on the result, loosening load calculated by Tcrzaghi tunnel theory is much greater than numerical analysis results. And the load calculated in weathered soil is lager than weathered rock condition. As in-situ stress ratio increases, the stress acting on the tunnel lining decreases in Terzaghi theory rapidly, whereas there is little effect in numerical analysis. |
