摘要
以北川县永安镇开发区的路网软基处治工程为研究场地,结合监测数据,研究了强夯置换对周围土体的挤压效应、夯沉量、孔隙水压力,并应用静载试验验证处理路基的承载力特征值。经过试验路段研究表明,该法适合在此路网中大范围使用。
Taking soft foundation treatment engineering of the road net in Yong＇an Town Development Zone, Beichuan County as the research site and combining with the monitoring data, the squeeze effect, settlement, and pore water pressure caused by dynamic replacement against the soil mass surrounded are studied; in addition, the characteristic value of bearing capacity of the s research on test section shows that the method is applicable in ubgrade is verified by static loading test. The this road net to a large extent.
