低高度PPC简支梁桥工程实践

随着高强钢绞线、新型锚具等现代预应力技术的发展以及施工技术水平的提高，低高度PPC梁（注：即部分预应力混凝土梁）的应用日益广泛，它不仅能够降低构筑物的建筑高度、缩短构筑物的长度、减少占地拆迁面积和工程造价，而且在景观上也具有良好的效果。本文以实例介绍其设计构思。

Practice of Low PPC Simple Supported Beam Bridge Projects

With the development of modern prestress technique like high strength strands, and new type anchorage devices, and rising of construction workmanship, the low PPC (i. e. partially prestressed concrete) beam has found more and more extensive application. Not only can it lower the construction height of the structure, shorten its length, and minimize the occupied land area and construction cost, it can also achieve good result in landscaping, Here introduced is tile design philosophy of such bridges.
