摘要
分析桥梁桩基采用后压浆技术提高桩基承载力和降低桩顶变形的作用机理,并对某施工现场进行不同成孔工艺的桩基静载承载力试验以及压浆桩与未压浆桩的受力对比试验,对后压浆技术的施工效果加以验证。
The paper analyzes the mechanism of the post-grouting technology to increase the pile＇s bearing capacity and decrease the pile＇s sedimentation. Meanwhile, the bearing capacity tests of different hole-making technologies and the force comparison tests of the grouting piles and non-grouting piles are used to verify the construction effects of the post-grouting technology.
