某水库泄洪工程进水塔为大体积的混凝土结构，体型、受力情况及边界条件都较复杂，塔体下部具有较大孔口泄洪引水流道，基岩较软．根据进水塔的结构特点，利用空间块体单元对进水塔进行有限元离散，计算了该进水塔在７ 种工况下的强度与变形，给出了几个典型截面的应力等值线图，得出一些可作为设计依据的有益结论．
The inlet tower of a reservoir spillway project is a large-volume concrete structure. The body shape, force conditions and boundary conditions are complicated. The lower part of the tower body has a larger orifice for flood discharge and diversion, and the bedrock is softer. According to the structural characteristics of the inlet tower, the space block unit was used to conduct finite element discretization of the inlet tower. The strength and deformation of the inlet tower under seven conditions were calculated. The stress equivalent of several typical sections Line drawings, come to some useful conclusions as a basis for the design.
