摘　　要：某近岸无掩护式集装箱码头后方地基由软土碎石堆载形成,地基不稳定。由于外界条件变化和仪器观测精度的限制,监测数据经常出现波动。研究在此不利条件下保证变形监测的精度和质量的方法,并从错综繁杂的数据来判断承台位移趋势,及时提出预警信号。The back foundation of a near-shore unsheltered container wharf was unstable since it was formed by soft soil and crushed stone.Due to the change of external conditions and the accuracy limitation of the monitoring instrument,the monitoring data often fluctuated.This paper probes into the way of guaranteeing the monitoring accuracy of deformation and adjusting the platform＇s displacement trend based on a various kinds of data,so as to give the early warning signal timely.

关 键 词：变形监测 精度 波动 位移趋势
