In order to investigate the influence of smoke traps on the components of mainstream smoke,the total particulate matters were collected with Cambridge filter and electrostatic trap,respectively.

Research on modifying Cam-clay model considering shear deformation;

The Cam-clay model has widely been used in the last decades which described the main features of soil elastic-plastic stress-strain relationship.

In consideration of the fact that the Cam-Clay model is incapable of reflecting the deformation characteristics of initially anisotropic soil,and that the Ohta-Sekiguchi model can reflect the initial anisotropy of soil to some extent by adoption of a new stress ratio,the two models are modified by readjustment of the yielding locus and hardening axis in p-q plane.

Modern Academic Functions of World-leading Universities ——A Case of the University of Cambridge in UK;

Revised Cambridge model is incoporated in the procedure for modelling elasto plastic behavior of the so.

The Cambridge model isexpanded to the case of unsaturated soil by the use of effective stress.

Research conclusions:The Cambridge model belongs to the isotropic hardened elastic model,which is adaptive to the soft soil in the subgrade experiment section of Beijing-Tianjin Intercity Railway with consideration of the water-press yield characteristics,the press rigidity,the shearing shrinage and the effects of load and download.
