摘　　要：通过对54根管桩静载荷试验快速法与慢速法对比试验研究,找出了在各级荷载作用下,快速法与慢速法沉降差异规律及快速法与慢速法分别得出的极限承载力差异规律;得出了将快速法静载试验下的沉降及单桩极限承载力修正成慢速法静载试验的沉降及单桩极限承载力的公式;提出了适应天津地区管桩的快速法静载试验方法。On the basis of the method comparison study between quick and slow load static test from 54 pipe piles, the settlement difference rule between quick and slow load in every grade was obtained, the difference rule of the ultimate bearing capacity from quick and slow load test was achieved, the conversion formula of the settlement and the ultimate bearing capacity from quick load to slow load test was derived. And a quick load test method of pipe pile suitable for Tianjin area was presented in this paper.
