Researches on calculation methods of rock resistant coefficients of submarine tunnels

    摘要
  • 摘要: 针对厦门海底隧道地质条件复杂多变的特点,利用有限环模型结合多种本构关系提出了7种围岩抗力系数K的计算方法,并且通过计算给出了合理的围岩抗力系数取值范围,同时对各计算模型在实际工程中的运用条件作了评价。研究结果表明:采用多种方法、综合考虑多种因素可以减少仅仅通过查阅规范和依靠设计者经验来确定围岩抗力系数的主观误差。

     

    Abstract: Considering the complexity of geological conditions for the Xiamen submarine tunnel,seven calculation methods were deduced to determine the rock resistant coefficients by use of the finite ring model,and reasonable range for rock resistant coefficients was provided too,together with the applicability of these seven methods respectively.It was indicated that comprehensive consideration could minimize the error in determining the value of rock resistant coefficients.
