Field experimental study on pile-soil stress ratio of pile-net composite foundation under embankment

Field study of bearing behavior of pile-net composite foundation

According to the actuality of lacking relevant data, two experimental section are designed to investigate the change mechanism of pile-soil stress ratio of pile-net composite foundation .

Design of the treatment of loess foundation with the pile-net composite foundation;

Determination of the stress ratio of pile and soil of pile-net composite foundation;

The application of pile-net composite foundation of cement injection pile in expressway soft foundation reinforcement can ensure that the cement injection piles exert their effction of load-bearing adequately,and the number of piles will not be large,thus the projects will be more economical.

Numerical simulation and comparison of pile-net composite foundation with pile-supported embankment;

Discussion of cushion in composite ground;

Application of pile-web complex foundation in the highway salty soil treatment;
