摘　　要：通过水准仪观测以及传感器监测等方法对高水位条件下低路堤路基的湿度、土压力及沉降进行监测。结果表明,土体湿度、土压力及沉降受周围环境、气候条件及周边土体影响,平衡时湿度接近30约为30%,5个月后土压力趋于稳定,土压力值约为22.7 kPa,8个月后路基沉降趋于稳定,沉降值约为8.34 mm。低路堤路基技术在应用时应做好隔水措施。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.
