Soil arching effect-based heaving-control shallow-buried tunnel underground structure and construction method thereof
The invention discloses a soil arching effect-based heaving-control shallow-buried tunnel underground structure and a construction method thereof. The heaving-control shallow-buried tunnel underground structure comprises a groove; the tunnel is located in the groove; the soil body burying layer is located in the groove and covers the tunnel; the lower arch-shaped piece is arranged in the soil body burying layer and is positioned above the tunnel; the lower arch-shaped piece is arched towards the tunnel; and the upper arch-shaped pieces are positioned in the soil body burying layer and are symmetrically arranged above the lower arch-shaped pieces. The tunnel is adopted, the lower arch-shaped piece and the upper arch-shaped piece are sequentially arranged above the tunnel to support the soil body above the tunnel, and the characteristics of the arch-shaped structure are utilized to reduce the sinking of the ground and reduce the upheaval of the soil body above the tunnel, so that the upper stress of the tunnel structure is weakened; it is guaranteed that the structure is not deformed or damaged, and the purposes of improving the safety coefficient and reducing the safety risk are achieved.
本发明公开一种基于土拱效应的控隆沉浅埋隧道地下结构及其施工方法，其包括：沟槽；隧道，位于所述沟槽内；土体掩埋层，位于所述沟槽内、并覆盖所述隧道；下位拱形件，布置于所述土体掩埋层内、并位于所述隧道的上方；所述下位拱形件朝所述隧道拱起；上位拱形件，位于所述土体掩埋层内，并对称布置于所述下位拱形件的上方。本发明中采用隧道，并在所述隧道的上方依次布置所述下位拱形件和所述上位拱形件，对所述隧道上方的土体进行支撑，并利用拱形结构的特性，减少地面的下沉，降低所述隧道的上方的土体隆起，从而减弱隧道结构的上部应力，保证结构不发生变形和损坏，达到提升安全系数、降低安全风险的目的。
