Study on Performance Evolution of Low Embankment Subgrade under High Groundwater Level
The moisture,earth pressure and settlement of low embankment subgrade under the high groundwater level are observed and monitored by means of level gage and sensor.The results show that the soil moisture,earth pressure and settlement are affected by the surrounding environment,climatic conditions and surrounding soil.The humidity is close to 30 at equilibrium,about 30%.After 5 months,the earth pressure tends to be stable,and the earth pressure value is about 22.7 kPa.After 8 months,the subgrade settlement tends to be stable,and the settlement value is about 8.34 mm.The waterproof measures shall be taken when the low embankment subgrade technology is applied.
