本文按上期的分析方法,对无中间横梁的预应力混凝土简支梁桥进行设计,并与原来有中间横梁的简支梁桥作比较。以建设省标准设计(1979年制定的)为设计对象,其中先张法T形梁桥有2种,后张法T形梁桥有3种,是跨径为15～35m的预应力混凝土简支梁桥。根据材料计算,求得概略的工程费用,并对有、无中间横梁情况的经济比较
In this paper, according to the previous analysis method, the prestressed concrete simply supported girder bridge without intermediate beams was designed and compared with the original simply supported girder bridge with intermediate beams. According to the standard design of the construction province (formulated in 1979), there are two kinds of pretensioned T girders, three of post-tensioned T girders, and the prestressed concrete with a span of 15 ~ 35m Beam bridge. According to the material calculation, the approximate project cost is obtained, and the economic comparison of the situation with and without intermediate beams
