有土模侧限的预应力混凝土大梁设计与施工方法研究

介绍了哈尔滨医科大学游泳馆场地情况及工程概况，探讨了该工程逆做法的施工顺序及方法。对材料选择、预应力工艺选择、荷载取值、预应力线型、内力计算等进行了分析，指出了按现行方法不考虑土模侧限进行设计存在的问题，建立了较合理考虑土模侧限对预和混凝土大梁应力传递及设计计算结果影响的方法，为设计建造哈尔滨医科大学游泳馆工程提供了理论依据，这项工程的设计建造为建设同类工程提供了范例。

The Design and Construction Study about Prestressed Concrete Beam under Soil-confined Effect

This paper introduced the site and general situation of the natatorium engineering at Harbin Medical University. It discussed the order and method of construction and analyzed the choice of materials, technology of prestress, prestressed bars' shape and the internal force calculation. The authors pointed out some problems in design according to the present method which did not consider the con fined effect of soil. A reasonable method of considering confined soil which effects the stress transmis sion and the design principle are found, which provides a rationalized foundation for designing and constructing the natatorium at Harbin Medical University. In addition, this work provides an example for the same engineering.
