Control Method of Soil Settlement Around Rock-filled Subgrade of Concrete Continuous Bridge
In order to avoid the hidden danger of traffic safety caused by the settlement of bridge subgrade,the control method of soil settlement around the rockfill subgrade of concrete continuous bridge is studied.Select appropriate rockfill materials through the change of soil stress around the rockfill subgrade,and compact the soil and stone with vibration compaction method to control the settlement of soil around the rockfill subgrade of concrete continuous bridges.The results show that under the same pressure,the soil around the rockfill subgrade can be compacted easily by the rockfill material with smaller particle size;When the slope ratio of the soil around the rock fill subgrade is 1 ∶ 1.8,the soil stability coefficient is the highest;The settlement is controlled by compacting the soil around the rock filled subgrade,and the porosity and settlement rate meet the compaction standard of subgrade design specifications;The settlement value of soil around the rockfill subgrade is low one year after the completion of the project observed by the inclinometer.
