摘要
由于受地质条件、填筑材料和加载时间的限制,在防波堤完工后会长期存在工后沉降。目前,在防波堤施工中多是通过预留沉降量来抵消防波堤的后期变形,对防波堤长期沉降规律的研究则较少。以采用爆破挤淤法处理的某抛石斜坡堤为例,归纳整理长期系统的防波堤实时沉降监测数据,分析总结防波堤长期沉降变形的规律,可供同类工程设计和施工参考。
Being restricted by geological condition, filled material and loading time, after-work settlement of breakwater always exists for long period. At present, settlement reservation method is generally used to counteract after-deformation of breakwater, but little research is carried out to get long-term settlement rule of breakwater. Based on one riprap sloping bank treated by blasting compaction, real-time settlement monitoring data are summed up systematically for long time, long-term settlement rule of breakwater is also analyzed and concluded, which will provide references for the design and construction of similar projects.
