Abstract: The potential for slope movement from pile driving is examined in this paper. Published information is reviewed to identify the primary causes of movement, which are 1) displacement of the ground as the pile penetrates, and 2) the effects of pore water pressure buildup created as the soil is compressed and sheared during pile installation. Approximate procedures for estimating the amount of movement and pore pressure buildup are given. The effects of pile driving on slope movement are then illustrated with two case studies, both of which involved driving piles in wharf slopes that had been instrumented. The results of these monitoring programs are reported and discussed, and the conclusions about the effects of pile driving on slope movement are presented.
