ABSTRACT = {In 
this 
paper, 
an 
analytical 
solution 
is 
developed 
to 
investigate 
soil 
consolidation 
around 
a 
pile 
under 
earthquake 
loading. 
The 
solution 
is 
validated 
using 
finite 
element 
method. 
The 
influence 
of 
various 
parameters 
on 
excess 
pore 
water 
pressure 
is 
analyzed. 
The 
results 
show 
that 
excess 
pore 
water 
pressure 
increases 
with 
depth 
and 
is 
positively 
correlated 
with 
n
and 
N<sub>eq</sub>
/
N<sub>1</sub>
, 
while 
negatively 
correlated 
with 
η
, 
χ
, 
k<sub>v</sub>
, 
and 
t<sub>d</sub>
. 
The 
values 
of 
η
, 
χ
, 
k<sub>v</sub>
, 
N<sub>eq</sub>
/
N<sub>1</sub>
, 
and 
t<sub>d</sub>
affect 
excess 
pore 
water 
pressure 
during 
and 
after 
the 
earthquake, 
while 
the 
value 
of 
n
only 
affects 
excess 
pore 
water 
pressure 
after 
the 
earthquake. 
The 
growth 
rate 
of 
excess 
pore 
water 
pressure 
during 
the 
earthquake 
is 
positively 
correlated 
with 
n
, 
η
, 
k<sub>v</sub>
, 
and 
N<sub>eq</sub>
/
N<sub>1</sub>
, 
and 
negatively 
correlated 
with 
χ
and 
t<sub>d</sub>
. 
The 
dissipation 
rate 
of 
excess 
pore 
water 
pressure 
during 
the 
earthquake 
is 
positively 
correlated 
with 
η
, 
χ
, 
k<sub>v</sub>
, 
N<sub>eq</sub>
/
N<sub>1</sub>
, 
and 
t<sub>d</sub>
, 
and 
negatively 
correlated 
with 
n
. 
Additionally, 
a 
formula 
for 
calculating 
the 
reconsolidation 
settlement 
of 
pile-soil 
foundation 
after 
an 
earthquake 
is 
proposed, 
and 
the 
effects 
of 
pile 
and 
soil 
parameters 
on 
pile-soil 
foundation 
reconsolidation 
settlement 
are 
analyzed. 
The 
results 
indicate 
that 
reconsolidation 
settlement 
can 
be 
divided 
into 
two 
stages: 
rapid 
settlement 
stage 
and 
slow 
settlement 
stage. 
The 
total 
settlement 
of 
the 
foundation 
is 
positively 
correlated 
with 
n
, 
η
, 
and 
N<sub>eq</sub>
/
N<sub>1</sub>
, 
while 
negatively 
correlated 
with 
χ
, 
k<sub>v</sub>
, 
and 
t<sub>d</sub>
