In the early 1960s of 20th,The vibro-flotation started in Germany used to reinforce clay foundation started in Germany used to reinforce clay foundation, since the filler is gravel ,so called gravel pile, after which ,in the national practical engineering application[1].Because of its short construction period, a relatively small investment and construction techniques such as the lack of conditions, it can be used in port and pier foundation treatment methods and techniques which is relatively small.
Determine the factor set The factor set U =（）={ supporting course,The pile density,Pile diameter, Pile-soil stress } The subclass factor set = ()={Soil natural weight, The Characteristics of bearing capacity of the soil, The physical properties of soil, The compressibility modulus} =（）={The hammering number, The proportion of gravel and soil} =（）={ Depth of bearing stratum, construction technique, ground bearing capacity} =（）={ The Soil compactness, The physical properties of soil, pile spacing } We applied the evaluation system above it, Combined with the engineering geological exploration and pile body in the drilling case report, The Comprehensive evaluation of the stability of the system is 31.368,The Security and stability level is V3, It indicates that the system for the general safety.
We can get the weight coefficient of each evaluation index and also can be obtained accurately. ②The model established in accordance with the actual in our engineering situation, it is beneficial to promote the study of some practical engineering problems in actual project, The method is applied more widely in the evaluation of safety engineering. ③The Combination of multiple methods is a good development trend for the practical application of mathematical modeling.

Dynamic accumulation damage characteristics of initial cracks for the lining of high-speed railway’s tunnel Xiangqiu Wang1,a, Bin Cai2,b 1 Dept. of Civil Engineering, Foshan University, Foshan,528000, China 2Faculty of Civil Engineering of Guangdong University of technology ,510006，China atongji_wxq@163.com,b864353786@qq.com Keywords: tunnel of high railway, initial damage of lining structure, mechanism of cumulative damage, theory of linear elastic damage Abstract: After have been analysed the initial dynamic cumulative damage mechanism of lining structure of the high speed railway tunnel,the conclusions have been gained that, under the effect of the long-term vibrating load of high speed train, When the damage energy accumulation reached a limit values, the damage zone caused by the initial crack which has been existed in the tunnel lining will be expansed further more. for the more, based on the accumulation damage theory linear elasticity and the analysis method dynamic finite
Stress intensity factor of initial Damage crack The engineering practice shows that the initial cracks of tunnel lining mainly belongs to the tension crack, even though the forms of them are complex and diverse.
The calculation results accord with the practical engineering[8].
Based on the cumulative damage theory of the linear elastic fracture mechanics and combined with the finite element method which can consider the dynamic interaction between the surrounding rockmass and the lining structure of tunnel, the fatigue cumulative damage characteristics of tunnel’s lining structure can be calculated reasonably and its results can satisfied to the practical engineering.
