摘　　要：为了明确大筒径的地埋式一体化预制泵站的筒体强度变化规律,采用数值模拟方法对地埋式一体化预制泵站的筒体进行了数值计算,分析了不同水位、不同材料及不同壁厚时筒体的应力应变。结果表明:不同水位工况时筒体的最大应力均位于筒体与底部交接处,且水位越低,筒体最大应力越大,最大应变也越大。相同工况时,筒体最大变形位移均随着筒体壁厚的增大而减小。相同壁厚时,随着筒体内水位的增加而筒体最大变形位移逐渐减小。相同壁厚时筒体材料建议采用玻璃钢。In order to clarify the variation law of the cylinder strength of the buried integrated prefabricated pumping station with large cylinder diameter,the numerical simulation method was used to calculate the cylinder of the buried integrated prefabricated pumping station,and the stress and strain of the cylinder under different water levels,different materials and different wall thicknesses were analyzed.The results show that the maximum stress of the cylinder is located at the junction of the cylinder and the bottom under different water level conditions,and the lower the water level,the greater the maximum stress of the cylinder and the greater the maximum strain.Under the same working conditions,the maximum deformation displacement of the cylinder decreases with the increase of the wall thickness of the cylinder.When the wall thickness is the same,the maximum deformation displacement of the cylinder decreases gradually with the increase of the water level in the cylinder.When the wall thickness is the same,glass fiber reinforced plastic is recommended for cylinder material.
