为分析顶管法联络通道在大偏角工况下的适应性，以某工区顶管法联络通道项目为背景，在偏移夹角为5°的情况下，结合现场实际情况，从特殊衬砌环受力情况和设备局部优化改造方向进行分析。通过研究得到以下结论： 1）由于联络通道处特殊衬砌环的拼装误差，会导致掘进机主机轴线与推进轴线偏移夹角出现大于3°、小于7°的情况，影响正常施工； 2）通过构建的主隧道有限元模型，静力分析得出在施加最大顶推水平和垂直分力的情况下特殊衬砌环受力满足要求； 3）通过对设备的顶推系统、洞内吊装运输系统、拖车平台等进行局部优化改造，突破了顶管法联络通道设备最大偏移夹角3°的限制，消除了特殊衬砌环拼装误差的影响，拓展了顶管法联络通道的适应范围。

To examine the adaptability of connecting gallery using pipe jacking method under large deflection angle, a case study is conducted on a connecting gallery using pipe jacking method with a deflection angle of 5°. Analysis is conducted on the force of the special lining ring and the direction of local optimization and transformation of equipment. Conclusions are drawn as follows: (1) The assembly error of the special lining ring at the connecting gallery causes the deflection angle between the main axis of the boring machine and the propulsion axis rangeing from 3 ° to 7 °, affecting normal construction. (2) The static analysis using the established finite element model of the main tunnel show that the force applied on the special lining ring under maximum jacking force and vertical component force meets requirements. (3) Through local optimization and transformation of the equipment jacking system, the hoisting and transportation system in the tunnel, and the trailer platform, the normal construction is guaranteed, the influence of the assembly error of the special lining ring is minimized, greatly expanding the application area of the connecting gallery using pipe jacking method.
