| Abstract: | To a great extent,the veracity and reliability of soft foundation settlement estimation was determined by the veracity of calculating parameters.In order to reasonably selecting calculation parameters,comprehensive explorations were carried out in test points,such as sampling drilling,soil test and several in-situ test means.Through comparative analysis to the foundation soil parameters which obtained by different methods,relatively resonable parameter selecting method was put forward,it has a certain refer... |
