| Abstract: | The prototype measure was engaged for the stepped geogrid reinforced soil retaining wall in He-Long Highway roadbed wall section K29 307 to section K29 353 in Guangdong Province.The distribution of the reinforcement tie tensions,the lateral earth pressure distribution and it's changes with the thickness of the earthfill,the deformation of wall surface and the vertical base pressure were measured and analyzed.At same time,their influent factors and the change features were discussed.Then,some new views and useful conclusions are given. |
