| 摘 要： | 采用有限元法研究了埋藏式钢筋混凝土岔管的计算范围。研究中认为混凝土衬砌及围岩是线弹性体，并考虑了围岩不同弹性模量对计算范围的影响。算例给出了埋藏式钢筋混凝土岔管关键部位的应力受相关因素影响的情况。最后通过综合分析得出了埋藏式钢筋混凝土岔管的有限元计算范围值。

| Abstract: | FEM is used to study the calculation range of the underground concrete.lined bifurcated pipes.The elements of the concrete lining and the surrounding rock are assumed to be linear elastic,and the influence on calculation range of different elastic modulus of the surrounding rock is considetal. Influence on stresses at the key locations of the bifurcated pipes by correlation factors are given.And the value of the calculation range of the underground concrete lined bifurcated pipes is obtained. |
