Karst region ductile anti-collapse roadbed structure and construction method of Karst region ductile anti-sag roadbed structure
The invention relates to a Karst region ductile anti-collapse roadbed structure and a construction method of the Karst region ductile anti-collapse roadbed structure. Through the use of reticular gabion structures, the ductile anti-collapse capability of the roadbed structure is greatly improved. When small-size collapse pits with the diameter smaller than 1m appear on the ground, no influence is generated on the reticular gabion structures; and when small-size collapse pits with the diameter being 1m to 3m appear on the round, the gabion structures can fill and block Karst channels, so that the collapse slowly stops. When larger collapse pits appear on the ground, slumps occur at a small part of the gabion structures, and as the reticular gabion structures are mutually bound by steel bars, so that large-area slumps cannot occur; besides, a continuous arch structure has better capability of adapting to unfavorable geology, so that the roadbed structure still has good stability to support the pavement structure, thereby preventing collapse. Therefore the Karst region ductile anti-collapse roadbed structure is suitable to be popularized and used in a large area. The construction method comprises the steps of sequentially laying a cement soil sealing layer, the reticular gabion structures, a soil pad layer and the continuous arch structure, and the Karst region ductile anti-collapse roadbed structure is finally obtained.
