Abstract

Abstract

The settlement deformation characteristic and load transfer mechanism of pile-net reinforced embankment are studied through the 3D model test,considering the factors of embankment height,width and clear spacing of pile cap,residual consolidation settlement,compression modulus of soil between piles and geotextile.Some useful test conclusions are obtained.The results of model tests are compared with the calculated results of analytical methods.The results show that for 3D situation,the results obtained from BS 8006's,adapted Terzaghi's and Hewlett's methods are in fair agreement with the results of model tests.And the calculated results of analytical methods are well agreed with the results of model tests with the increasing of width of pile cap.However,the adapted Guido's and Carlsson's methods overestimated the efficiency.The conclusions may be a valuable reference for the design of pile net reinforced embankment.
