AN EXAMPLE OF DYNAMICS RESPONSE CALCULATION OF DAM FOR SLOPE SAND CONTROLLING

The dam located on an open-cut side slope in Shuilongshan-Yangtaowu,falls into a light-duty one in reinforced concrete structure for sand controlling.The paper,considering the dynamic loading impact resulted from the frequent mining blasting operation on the dam,simplifies the dam to one degree of freedom system for dynamic analysis.With the help of Simpson formula,the numerical value calculation of dynamics response of dam is made,educing basic parameters of dynamics displacement and elastic restorable force.The outcome lays an important foundation for structure design and durability investigating of dam structure in its normal service period.
