Abstract
To study the influence of soil and water loads on the main stresses and displacements of the pump station under dif-ferent operating conditions,the Zhangdu water intake station of the Changshan reservoir replenishment project in the Simashan irrigation district was taken as an example.A 3D finite element model of the pump station was established using MIDAS GTS NX software.The modified Mohr-Coulomb constitutive model was used to compare the distribution results of the main stresses and displacements of the pump station under different conditions with the specified limit values in the standards.This analysis revealed the relationship between the main stresses and displacements of the Zhangdu water intake station under varying oper-ating conditions.The maximum displacement and structural stress at the station both met the standard requirements.The maxi-mum displacement under different operating conditions changed minimally,primarily because the settlement of the station body had stabilized after completion,and the impact of water level changes was small.The maximum principal tensile stress of the pump station sluice pier varied little under different operating conditions.However,the maximum principal tensile stress at the pump station's bottom slab was significantly influenced by changes in operating conditions.Therefore,the strength design of the bottom slab should be given special attention during the design phase to prevent tensile failure of the bottom slab.关键词
