摘要

Through indoor consolidation test and CPTU model test and CPTU in-situ test, the soil consolidation coefficient has been studied. Compared with the consolidation coefficient by indoor test equipment and CPTU, because in-situ test has been made by CPTU, but in indoor consolidation test the error caused by the disturbance and little size of clay soil sample has been existed, the soil consolidation coefficient by CPTU can reflected the soil consolidation characteristics more accurate than by indoor consolidation test. Compared with the consolidation coefficient by remolded clay soil of CPTU model test and the natural and un-disturbed clay soil of CPTU in-situ test on CPTU application research project on Pearl River Delta, the dissipation speed of excess pore pressure in CPTU model test is iaster than in CPTU in-situ test;;the horizontal consolidation coefficient value of clay soil by CPTU model test and CPTU in-situ test is close in the same magnitude order. The test result by CPTU model test is close to the result by CPTU in-situ test. The achieved result can provide a foundation for further study for soil consolidation coefficient by CPTU.
