This paper presents a method for analysis of stress and strain of gas pipelines under the effect of horizontal catastrophic landslides. A soil spring model was used to analyze the nonlinear characteristics concerning the mutual effects between the pipeline and the soil. The Ramberg–Osgood model was used to describe the constitutive relations of pipeline materials. This paper also constructed a finite...
The indoor triaxial data indicate that rheological deformation of asphalt concrete is large under complex stress, the proportion of which is about 30% in total measured deformation. In this paper, the incremental model based on rheological heredity theory is applied to study of operation character of Yele asphalt concrete impervious structure, and the rationality of incremental model is verified with...
In this paper, following work were made: the ground acceleration inputted was determined combined with the acceleration of Wen Country seismic station during Wenchuan Earthquake, and dynamic parameters of dam materials were determined by analogy with the information of large-scaled indoor triaxial experiment of Shuangjiangkou, Changheba, Luding and Nuozhadu projects. Then, a dynamic analysis of dam...
