According to the deficiency of the strain accumulating and releasing curves and the previous models, the strain-accumulating rate of the strain accumulating and releasing model has been deduced based on the G-R relation and the empirical formula between energy release and earthquake magnitude, where the strain-accumulating rate is relative independent of the strain-releasing rate.

By use of horizontal velocity data observed by GPS during 2001—2004 and 2004—2007 in the northeastern margin of Qinghai-Tibet block,aided by the negative dislocation model,the characteristics of horizontal crustal movement and the status of strain accumulation of this area are researched and following conclusion are drawn.

By use of the regional leveling and GPS observations in Sichuan-Yunnan area during 1994-2006,aided by the negative dislocation model for the elastic block boundaries,combining with the total characteristics of deformation cross-fault,the recent status and intensity of strain accumulation of tectonic blocks and their boundary faults in Sichuan-Yunnan area are studied.

Experimental study on effect of shear strain accumulation on dynamic shear modulus and damping ratio of clay soil;

The key point of study was focused on the behaviour of cumulative strain rate.
