Open cut tunnel soft foundation comprehensive reinforcing structure
The invention provides a comprehensive reinforcing structure for a soft foundation of an open-cut tunnel, which comprises enclosure walls and a reinforcing structure, the enclosure walls are respectively arranged on two sides of a main body structure of the open-cut tunnel, and the enclosure walls penetrate through the soft foundation and are inserted into a bearing stratum; a plurality of resisting structures are arranged on the outer side of each enclosure wall, and the bottoms of the resisting structures are inserted into the bearing layer; the shear-resistant supporting structure is located between the two enclosure walls, the shear-resistant supporting structure is located below the open cut tunnel body, and the bottom of the shear-resistant supporting structure is inserted into the bearing stratum; and the anti-floating structure is located between the two enclosure walls, the two ends of the anti-floating structure are connected with the enclosure walls on the two sides correspondingly, and the anti-floating structure is located above the open cut tunnel body. In the reinforcing structure, under the combined action of the resisting structure arranged on the periphery of the enclosure wall, the shear-resistant supporting structure arranged below the open-cut tunnel main body and the anti-floating structure arranged above the shear-resistant supporting structure, the safety and stability of the open-cut tunnel main body structure are guaranteed.
本发明提供一种明挖隧道软弱地基综合加固结构，加固结构包括：围护墙，在明挖隧道主体结构两侧各设置有一道围护墙，围护墙贯穿软弱地基，且插入至至持力层中；抵抗结构，在每道围护墙的外侧均设置有多个抵抗结构，抵抗结构底部插入至持力层中；抗剪支撑结构，抗剪支撑结构位于两道围护墙之间，且抗剪支撑结构位于明挖隧道主体下方，抗剪支撑结构的底部插入至持力层中；抗浮结构，抗浮结构位于两道围护墙之间，抗浮结构的两端分别连接两侧围护墙，且抗浮结构位于明挖隧道主体上方。在该加固结构中，在围护墙外围设置抵抗结构，以及明挖隧道主体下方设置的抗剪支撑结构以及其上方设置抗浮结构的综合作用下，保证了明挖隧道主体结构的安全稳定性。
