Finally , respect to the beam effect induced by special high ratio of modulus of elasticity of baise gravity dam , the sensitivity analysis are carried out to study the relation among displacement , stress state of dam and rock bed parameters 最后,針對百色重力壩特殊的高彈模比地質(zhì)條件所致懸臂效應,對壩體及壩基的變形和應力狀態(tài)與壩基力學參數(shù)之間的關系進行了參數(shù)敏感性分析。
