摘要
通过对桩端置于含泥圆砾卵石层超短静压预制桩桩底注浆及注浆前后静载试验,分析了桩竖向极限承载力的提高机理。试验表明,桩底注浆可较大幅度地提高以砂卵石为持力层的静压预制桩的竖向承载力。
In-situ tests of the behaviour of grouting under tip of precast concrete short piles in sand and gravel layer were performed and The test process was presented in details. The results of bearing capacity tests of short piles in sand and gravel before and after grouting show that the vertical ultimate carrying capacity of single grouted precast concrete short pile in sand and gravel layer can be enhanced very much.
