摘要
将影响偏压隧道结构稳定性的因素概括为4个指标,即围岩超欠挖量、隧道稳定性系数、地震烈度和隧道偏压比。然后对每个指标收集若干组原始数据信息。利用原始数据,根据信息优化理论建立原始数据信息与偏压隧道结构稳定性关系,对结构稳定性进行评价,经过计算分析和工程检验,证实了该方法的可靠性。
The stability of unsymmetrically loaded tunnels is studied using four indexes, such as overbreaking of rock, ratio of unsymmetrical load, earthquake rank and stability coefficient. Some original data about each index are collected. The relation between structural stability of unsymmetrically loaded tunnel and original data is established with the help of the information optimization theory, and the tunnel stability is evaluated with these data. The method is proved credible by field measurements.
