[0023] The present invention is a wedge-shaped geocell cement-reinforced soil structure for road and bridge connection such as figure 1 As shown, it includes cement stabilized soil 4, filler, and geocell 3. One end of the geocell 3 is fixed on the back of the bridge and culvert abutment 2, and the other end is fixed on the roadbed 5. The geocell 3 is arranged in parallel from top to bottom. , The two adjacent layers of geocells 3 are filled with filler and cement stabilized soil 4. The cement stabilized soil 4 is filled in the end of the geocell 3 near the back of the bridge and culvert abutment 2. The length of the cement stabilized soil on the top layer is 1 of the length of the geocell / 2~3 / 4, the other filling materials, cement stabilized soil 4 and the length of the geocell 3 decrease layer by layer from top to bottom to form a wedge or ridge.
[0024] Preferably, the decreasing slope of the cement stabilized soil 4 and the geocell 3 is 1:1. The definition of the decreasing...
