Study on Creep Characteristics and Constitutive Relation of Fractured Rock Mass
Shock and Vibration, 2020 In order to effectively describe the whole creep process of fractured rock mass, triaxial unloading creep tests were carried out on prefractured coal samples using constant axial pressure and graded unloading confining pressure, and the axial and lateral

Creep and Hardening Characteristics of Anthracite under Graded Static–Dynamic Coupled Loading
Applied Sciences, 2023 Remaining coal pillars in remining areas exhibit clear creep characteristics, and dynamic pressure accelerates their instability and failure. The creep and hardening characteristics of coal under dynamic pressure are of great engineering significance for

Experimental Research on Creep Characteristics of Nansha Soft Soil [PDF]
The Scientific World Journal, 2014 A series of tests were performed to investigate the creep characteristics of soil in interactive marine and terrestrial deposit of Pearl River Delta. The secondary consolidation test results show that the influence of consolidation pressure on coefficient of secondary consolidation is conditional, which is decided by the consolidation state.

A nonlinear creep model for surrounding rocks of tunnels based on kinetic energy theorem
Journal of Rock Mechanics and Geotechnical Engineering, 2023 The initiating condition for the accelerated creep of rocks has caused difficulty in analyzing the whole creep process. Moreover, the existing Nishihara model has evident shortcomings in describing the accelerated creep characteristics of the ...

Creep Characteristics of Sands
Soils and Foundations, 1984 ABSTRACT This study is concerned with the creep characteristics of sands under constant principal stress differences of various stress levels which were experimentally obtained by drained triaxial compression tests. In these tests, in order to obtain the creep behavior which is due only to the principal stress difference, but excluding the effect of ...
