Generally,it is reliable to test the integrity of foundatin pile structure by low-strain dynamical test. But while testing the
inclined pile due to landslide by low-strain in some sub-item of Tianwan Nuclear Power Station,the same pile of large displacement
shows different results by low-strain test in which some are broken or damaged, some are integrity. The test results are diffcult to
be identical with the practice. Considering that the pile isn' t isolated,but combined with the foundation soil, the excavation pit
support theory and circular sliding surface theory are used in combined with the construction practice,the possibility of pile frac-
ture,damage and incline,accordingly obtaining the correct adjustment to the inclined pile properties,and providing the foundation
for the engineering pile treatment.
