This article has introduced the necessity and particularity of technology of group-controlling and group-examination on the basis of main specific technology characteristics of electronic creep testing machines.

This article had proven the feasibility of electronic technology applied on the creep testing machines through the long time test.

Data processing and viscoelastic computation for creep test of asphalt mixture;

In order to study aluminum alloy creep age forming and present aluminum alloy creep constitutive model used in creep age forming FE simulation,7B04 aluminum alloy creep mechanical property was studied by carrying out creep tests under different stress levels at different temperature such as 145℃,155℃ and 165℃.

Uniaxial creep test had been carried out for 10CrMo910 steel at 550℃.

Based on the creep experiments for CE131 geonet and SDL25 geogrids,under long-term load and different load levels,the creep characteristic is studied.

Through the uniaxial compression creep experiment of surrounding rock of Qinling tunnel at different temperature, the creep law of the surrounding rock at different temperature was obtained in this paper,the creep model which can describe the property of surrounding rock was derived ,and the parameters of the model were determined by using experiment data.

Based on the uniaxial creep experiment with step-loading,the long term strength of pillar rockmass before grottoes No.

Based on the property of base course stabilized with asphalt, static creep testing is used to study the mixture with various kinds of gradation and asphalt volume.
