| Bank is an important part in Chinese system of controlling flood. It has accumulated much experience in the choice of bank's material, division of bank's body, stabilization of dam, seepage, settlement, analysis of stress and strain, treatment of foundation, criterion of reclamation and machine of construction and so on. But after many years running or for satisfying the need of economic development, many bank and its foundation has much disease, its normally use and benefit are naturally or man-madly influenced. According to status of HUXI Bank in XuZhou,JIANGSU province, using numerical value analysis theory and technique of dam construction, this paper put forward efficiency strengthen method in the base of study and analysis .The main work this paper do are these like below:(1) this paper reviewed and summarized the development and actuality of bank in china, induced the variety of bank's disease and the measure of judge etc.(2) The commonly used technology and method in bank's strengthen was summarized. Through analysis and compare, the measure fitting for HUXI bank was put forward.(3) Introduced Fast Lagrangian Analysis of Continua .FLAC3D is a three-dimensional explicit finite-difference program.. It can simulate the behavior of three-dimensional structures built or soil ,rock or other material and can simulate plastic collapse ,flow and large-strain accurately. In this it has its inimitable virtue.(4) Analysed the asymmetry settlement and thereout the crack because of excavating coal undergroundly oh HUXI Bank., then ascertained the magnitude of settlement and the distributing of the crack. Contrast to the observation data, the numeration is approach to the fact.(5) Through studying the real instance of HUXI Bank, put forward to corresponding reinforcement project. The result indicates that the reinforcement can satisfy the request of coast and penetrating stabilization.
