摘要
在濒海某场地的塑料排水带地基固结试验中,进行了孔隙水压力、沉降量、侧向位移等原型观测,并按沉降计算固结系数和固结度。固结结束后,用静力触探、十字板剪切仪、标准贯入和平板载荷试验检测处理效果。结果表明:排水带在很短的时间(50d内)使加固的地基达到固结稳定,说明在濒海软土地区采用排水带固结是有效的加固手段。
Observations of pore water pressure, settlement and lateral displacement were carried out and consolidation coefficient and consolidation degree were calculated based on the observed data in a foundation treatment with prefabricated strip drains at a seaside ground. The results of static penetration test, vane shear test, standard penetration test and plate load test after consolidation indicated reinforcements of foundation and increases of stabilization in 50 days. It is shown that the reinforcing foundation with prefabricated strip drains is an effective measure at seaside ground.
