摘要： 在极限设计中，如何确定结构的极限载荷对工程设计非常重要．通过实测应变和二倍弹性斜率法，对一台带椭圆形接管球形容器的极限载荷进行了试验研究，得到了该容器的最低极限载荷PL^T=9．48 MPa、爆破压力Pb^T=16.7 MPa，根据极限设计的方法，其设计压力P=6．32 MPa．试验结果表明：在未开孔补强的情况下，带椭圆接管球形容器的最薄弱部位在椭圆接管长轴与球体截交处靠球体侧，容器首先在该处爆破。

Abstract: In limit design，how to determine limit load of a structure is the pivotal job in engineering design．Research on limit load of spherical vessel with elliptical nozzle is conducted through testing the strain and adopting the method of double slope of elastic curve，and the results：minimum limit load of vessel-P=9．48 MPa，burst pressure-P=16．7 MPa，and design pressure according to limit design method-P =6．32 MPa．are achieved．These results indicates that under the circumstance of not opening reinforcement，the weakest area of spherical vessel with elliptical nozzle lies on the intersection of the major axis of elliptical nozzle and the spherical vessel，which is near the spherical vessel．In addition，the vessel always bursts there first too．
Key words: elliptical nozzle    spherical vessel    limit load
