摘要
Abstract
Relying on the project of dry jet mixing column for strengthening soft soil at a road site in Jiangsu province, the soils' excess pore water pressure and earth pressure during the process of construction were monitored when the speed of construction is fast, the pressure is larger. The test results show: the soils excess pore pressure decreases with distance from the column and dissipates in 1 hour after construction. When the construction sequence is faced the pile, the pressure is accumulated while is shielded when in the opposite direction. Compared with construction in sequence, the pressure is lower if doing skip construction. So selecting appropriate construction speed, sequence, direction and pile spacing for the dry jet mixing pile in soft soil site can decrease the excess pore water pressure effectively during the construction.关键词
