后注浆灌注桩在管桩基础中的补桩应用

Post grouting for cast-in-place pile as filling pile in the pipe pile foundation

依据后注浆灌注桩的单桩静载荷及桩周土阻力测试结果,对后注浆灌注桩及管桩的受力特征进行了对比分析,结果表明后注浆灌注桩的沉降受力特征与预制管桩相似,能够协调发挥承载力的作用。

According to the single pile after grouting piles static load of pile and soil resistance test results, of post grouting piles and the bearing characteristics of pile are analyzed in comparison, the result show that the settlement of post grouting piles bearing characteristics similar to precast pipe pile, able to coordinate the role of the bearing capacity.
