Mechanical deformation characteristics of hard rock in deep excavation Yinghui LVa, Bin YANb School of Civil Engineering and Architecture, University of Jinan, China acea_lvyh@ujn.edu.cn, bcea_Yanb@ujn.edu.cn Key words: unloading, constitutive model, failure criterion, hard rock Abstract: In the process of deep tunnel excavation, the surrounding rock mass, which often endures high initial geo-stress, is in the state of typical unloading.
In recent years, the demands of rock mechanics and engineering practices have accelerated studies on unloading failure of rocks.
Stress- strain curves of representative samples with different initial stress paths during unloading stage Rock failure criterion under the condition of unloading In geotechnical engineering, the Mohr-Coulomb criterion is the most commonly used in practice.

The designers of the engineering design must collect the area meteorological data and the causes and the flood hazard situations of the devastating flood disaster.
During the construction, we should pay more attention to the subsidiary engineering such as protection facilities of bridges and culverts, should have a strict construction according to the design.
Before the time of the flood, the management and maintenance departments should strengthen the comprehensive examination of bridges and culverts and should pay special attention to safety check of the drainage facilities and protection engineering of the small bridge and the culvert.

Active Seismic In recent years, engineers reduce earthquake seismic energy through the conversion, reduce the seismic forces exerting into buildings or use other methods to effectively reduce the response by the building after the earthquake.
To verify the durability of the laminated rubber heating engineer some quick tests to get a considerable number of favorable experimental data [6], may prove isolation bearings have good durability.
