The Resilience Deformation Rules Test Research of the Soft Soil in the Unloading Condition Bin Tang 1, 2, a , Ren Wang 1 and Jun Lei 2, b 1State Key Laboratory of Geomechanics and Geotechnical Engineering, Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, Wuhan, Hubei, 430071, China 2Urban Construction College of Wuhan University of Science and technology, Wuhan, Hubei, 430065, China atangbinruocheng@163.com, biwantoget@gmail.com Keywords: Soft soil, Unloading, Resilience deformation, Test research Abstract.
There is obvious difference between the engineering character of the soft soil in the unloading condition and loading condition.
The Soft Soil Used in the Test The soft soil in the test is from silt stratification in the Sixin region of the Wuhan New District, where large area of fishponds, lotus roots ponds and several irrigation ditches, which has the following basic physic indexes according to the laboratory civil engineering test: the water content is 42.0%～48.0%,the nature density is 1.78～1.81g/m3,the specific gravity is 2.71,the nature void ratio is 1.21～1.35,the liquid limit is 45.8～75.9,the plastic limit is 23.6～43.2.

The brittleness coefficeint of rock is equal to the ratio of the uniaxial compressive strength and uniaxial tensile strength in practical engineering.
Rock engineering has suggested that the weak rock joints has no inclination rock burst, rock burst often occur in structure is complete rock.
