随着我国经济建设的高速发展,目前我国对于公路桥梁的要求也在与日俱增。目前,在实际的公路桥梁建设的过程中,我国在大多数的情况下仍然是使用传统方法进行建设的,这种方法无法取得较好的效果,在公路桥梁建设完成后效果并不好,甚至还有可能产生一些安全事故,对我国人民的生命财产安全都造成较大的隐患,因此就需要使用一种全新的方法来对公路桥梁进行建设,预应力技术就是这样的一种方法。 With the rapid development of China’s economic construction, the demand for highway bridges in our country is also increasing at present. At present, in the process of actual highway bridge construction, our country still uses the traditional method to construct in most cases. This method can not achieve good effect. After the highway bridge construction is completed, the effect is not good or even It is also possible to have some safety accidents that pose a serious risk to the lives and property of our people. Therefore, a new method is needed to build bridges and bridges. Prestressing technology is one such method.
