双层滤管无砂垫层真空预压法处理超软海底吹填淤泥

针对沿海吹填成陆工程中的海底吹填淤泥场地地基承载力极低,无法进行后续建设施工的问题,通过现场对比试验,研究了双层滤管无砂垫层真空预压法在该类场地的应用.现场试验监测结果表明,双层滤管无砂垫层真空预压法取得的沉降大小和均匀度、孔压下降幅度和均匀度以及地基承载力等加固效果指标明显好于常规的无砂垫层真空预压法,因此双层滤管无...

Application of vacuum preloading method with double-layer filter pipe in non-sand-mat layer to ultra-soft seabed silt hydraulic filling

With consideration of the low bearing capacity of the ultra-soft seabed silt hydraulic fill sites in coastal areas and the huge challenge of continuing follow-up construction,the vacuum preloading method with a double-layer filter pipe in the non-sand-mat layer was applied and studied in these sites through contrastive field tests.The measured results from the tests show that the consolidation effect indices,including the size and uniformity of settlement,decline and uniformity of the pore water pressure,an...
