| 中文摘要:在地勘坑道施工中，由于岩层松散破碎，加上断层和裂隙发育，渗、漏水严重，已经支护好的坑道出现沉降，坍塌物将木支架压弯压折。补支护后，该区域由于地压过大又出现了沉降。存处理过程中应用托换技术进行了尝试，顺利解决了这一问题。介绍了伸缩式组合钢支架的设计制作以及处理过程。 |

| Abstract:In exploring tunnel, because of loose and broken of the stratum, in addition to fault and crack developing, seepage and leakage are serious, landslide occurs in supported tunnel, and wood support was curved and broken by falling pressure. After supplementary support, sinking emerged in the area. We tried to use underpinning, and the problem got solved successfully. Design and manufacturing of expanding combined steel support and the replacing procedure are introduced. |
