摘要
为保证防波堤施工过程中堤体地基和结构的稳定性,设置堤体沉降监测、戗台沉降监测和堤体孔隙水压力监测3个观测项目。结果显示:在施工初期,由于施工速度快、加载间歇短,造成地基出现瞬时沉降过大;堤体成型后,各监测数据区域稳定,变化速率缓慢,孔隙水压力的消散程度高。根据堤体实测沉降数据,通过双曲线法计算的土体固结度较高,地基稳定性好。
For the purpose of foundation and structure stability during the construction of tide embankment, three monitoring projects including embankment settlement monitoring, berm platform settlement monitoring and pore water pressure monitoring are installed. The result shows that foundation appears oversize instantaneous settlement on account of high construction speed, short loading interval at initial stage.Following with the shaping of embankment, stable monitoring data range, slow change rate and high dissipation speed of pore water pressure arise. Based on actual embankment settlement data, consolidation degree of soil mass is high and foundation stability becomes strong by calculating of hyperbolic curve.
