预应力技术是桥梁加固中应用比较广泛的一种建筑工艺,其操作简单、自重较轻、造价低廉、作用明显、安全可靠等特点,使得预应力加固技术在建筑工程领域加固方面发挥着巨大作用。由于预应力技术工艺方法各异,但基本原理比较简单,核心是面对具体桥梁,设计合适的加固方案,经济而实惠。本文就预应力的基本原理、发展状况和技术应用等方面,展开探讨,分析其中出现的问题,对加固方法必选原则提出一些观点和建议,旨在推动预应力技术在路桥施工中应用和发展。
Prestressed technology is widely used in bridge reinforcement construction technology, its simple operation, light weight, low cost, the role of obvious, safe and reliable, making the prestressed reinforcement technology in the field of architectural engineering plays a significant role in strengthening . Due to the different prestressed technology process methods, but the basic principle is relatively simple, the core is to face the specific bridge, design a suitable reinforcement program, economical and affordable. In this paper, the basic principles of prestress, development and application of technology and other aspects of the discussion, analysis of the problems that arise, the reinforcement principle of the proposed principles put forward some ideas and recommendations aimed at promoting the application of prestressed technology in road and bridge construction and development .
