随着桥梁跨度的不断增大,支座负荷会越来越大,因此,研制大吨位支座是桥梁技术中的一项重要课题。我们根据几年来的研究实践,对大吨位盆式橡胶支座(见图1)的若干问题提出一些粗浅的看法,特别是对国外某些 With the continuous increase of bridge span, bearing load will be more and more large. Therefore, developing large tonnage bearing is an important issue in bridge technology. Based on years of research practice, we put forward some superficial views on some issues of large tonnage pot rubber bearings (see Figure 1), especially for some foreign countries
