摘要：
夹坑隧道右洞进口位于软弱、偏压不良地质地段，施工过程中明洞地段发生了坍方，并影响到暗洞的施工。根据现场的地质情况，及时调整设计方案，对隧道地表进行导管注浆加固，并对暗洞支护措施进行了相应调整，增加了防偏压措施，顺利通过了软弱、偏压地段。对设计、施工措施及施工工艺、方法作了较为详细的介绍。

Abstract:
The entrance portion of the right tube of Jiakeng tunnel is located in soft ground with uneven pressure. During the construction of the tunnel, collapses occur at the open tunnel, which imposes impact on the construction of the underground tunnel. On basis of the geological conditions of the tunnel, the design proposals are timely adjusted, consolidation grouting is conducted from the ground surface, the reinforcement measures for the underground tunnel are adjusted and additional measures against the uneven pressure are taken, so that the construction of the tunnel portion in soft ground with uneven pressure is accomplished successfully. The article presents a detailed description of the design and construction of the tunnel.
