Field Tests on Composite Deep-Mixing-Cement Pile Foundation under Expressway Embankment
Anti-slide behavior of road foundation under embankment is of great importance to embankment stability in expressway engineering. Three kinds of field tests on anti-slide behavior of one expressway soft foundation improved by deep-mixing-cement pile (DMCP) are conducted, which include nature soft foundation test, single-pile foundation test and four-pile foundation test. Stress cells are placed in order to investgate the distributions of vertical stresses along the DMCP shaft during the filed tests. The investgated data show that anti-slide strength of the soft foundation increases greatly after the DMCP improvement. Single—pile foundation test and four-pile foundation test provide similar cohesion forces and friction angles, but they have different types of vertical stress growth process. Change of horizontal force only makes a little difference to vertical stress of DMCP below 6.0 m depth. This study can provide good base for relative design of expressway engineering.
