This paper introduces the forms of deformation damage to high-filled embankment as well as the reasons of damage.

The paper researched the stress fields and the deformation and breakage characters of rock mass in coal seam floor under the condition of mining, which is in order to establish definite theory base to discuss inrushing water mechanism in coal seam floor.

Therefore the study of the mining condion of rock layer s deformation and breakage characteristics is depth and perfect for water inrush mechanisms and controlling which has great theoretical and practical significance.

Lyapunov exponent of chaos feature in the processing of deformation failure for coal floor;

Study on fractal feature in the process of deformation failure for floor strata;

Main deformation failure patterns of bank slope in the middle-lower stream of the Yangtze river and countermeasures;

Non-homogeneity of the deformation and failure of the tunnel within weak rockmass and its controlling countermeasures;

Research on entropy catastrophic regularity and failure criterion in the deformation and failure process of rocks;

Study of deformation and failure of surrounding rockmass of underground excavation of hydraulic engineering in a city of Northwest China;

Three ways of the creep failure of the papersheet in the constant tensile loads including the creep of elastic failure, the creep of plastic failure, the creep of elastoplastic failure are described in this article.

The creep characteristics of frozen Lanzhou fine-sand and the impact of load vibration frequency on creep strain and creep failure are examined through a series of creep tests with different vibration frequencies.
