Research on Application of Gyro Pile Composite Sand Well Consolidation Drainage Technology in Expressway
In recent years,the consolidation and drainage technology of gyro pile composite sand well has been gradually applied to the soft foundation treatment of highway engineering.This technology not only has the advantages of expanding the load diffusion range and improving the uneven settlement of foundation,but also greatly shortens the stability period of overload preload.Consolidation and drainage of gyro pile composite sand well is a kind of shallow foundation treatment technology,which is especially suitable for soft soil foundation and sandy soil foundation in earthquake area.In this paper,the work behavior and stability of the ground before and after treatment of the gyro pile composite sand well have been compared with the common sand well treatment,the vertical settlement of the gyro pile composite sand well has been reduced by nearly 53%,and the settlement stabilization time has been saved by about 45%.The horizontal displacement of slope foot has been shortened by about 25%,which presents great engineering application potential.
