In this paper,deformation and failure modes and geological characteristics of its surrounding rockmass and construction of a deep-buried long tunnel in the ShangHai-ChengDu State Highways West Part of HuBei Province were investigated.

This paper presents the failure model of some diagonal slope with the interlayered silt mudstone,argillaceous sandstone and carbon shale by analysing the slope deformation character.

According to the practical geological engineering condition and deformation failure characteristic of the dangerous rock body of Lianzi cliff, the 8 deformation failure modes and displacement equations are summarized.

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;
