摘要
Abstract
The continuous large vibration generated during the construction of the pile will cause the soil to accumulate de-formation and increase the excess pore pressure,and cause the soil strength to decrease. Taking the slope of square as the background,we conduct a live vibration test. According to the dynamic stress generated by vibration,the in-suit stress state and stress path of soil element are simulated by static dynamic triaxial tests,and then we provided the test method and re-sults. Finally the reduction of soil strength under dynamic stress during construction is analyzed,which suggests that the strength reduction coefficient is 0. 7～0. 8.关键词
