| 摘 要： | 以某水电站工程为例,考虑钢衬与围岩间的缝隙值,按照钢衬与围岩联合承载,采用三维有限元方法对地下埋藏式钢岔管进行计算分析,讨论了围岩性能及初始缝隙值对围岩承载比的影响,并与明管计算结果相比较,指出在钢衬与围岩共同承受内水压力作用时,围岩发挥了重要作用.

| Abstract: | Through an illustration of a hydroelectric project, three-dimensional finite element analysis, in which the gap value between steel shell and surrounding rock is taken into account, are carried out according to the principle of interaction. The influence of surrounding rock performance and initial gap value on the load-carrying proportion of surrounding rock is discussed in comparison with the result of the exposed steel bifurcation, and the important function of surrounding rock is also indicated when steel shell and surrouding rock bear the internal water pressure together. |

| Keywords: | underground steel bifurcation load-carrying capacity of surrounding rock initial gap value boundary nonlinearity FEM |
