The anti-liquefaction-rigid-drainage pile is a new pile type combining the bearing capacity of rigid pile and the drain ability of gravel pile. In a pile foundation project

pile driving field tests of the rigid-drainage pile were carried out. The horizontal and vertical soil pressures around drainage piles and ordinary piles were recorded in different locations and depths using dynamic sensors during field tests. According to these test results

rigid-drainage pile can reduce the disturbance of soil pressures during pile driving. At the location 0.6 m far from the pile center in the depth -15 m

the peak horizontal soil pressure around the rigid-drainage pile is a quarter of the ordinary pile’s. The rigid-drainage pile can reduce the impact of pile driving on the effective stress in soil

which makes the liquefiable soil around rigid-drainage piles more stable. In the depth of -5 m

the effect of rigid-drainage piles on soil pressure is not obvious. In deep depths (-10

-15 m)

the effective influence radius of rigid-drainage piles is about 4 times as large as the pile diameter. The data of piles tests provide other engineers with reliable evidences.
