随着经济全球化的发展,人们的生活水平得到了很大的提高,对高速公路提出了新的要求,要求高速公路质量要在现在的基础上提高,确保人们的驾驶安全。在高速公路施工中,已经采用了钻孔灌注桩技术,不但提高了施工效率,而且还提高了施工质量。本文对钻孔灌注桩主要施工技术在高速公路施工中的应用进行分析,并探讨钻孔灌注桩优化技术处理常见问题。 With the development of economic globalization, people’s living standards have been greatly improved, and new requirements have been put forward on the expressway. The requirements of the expressway quality should be raised on the basis of the present to ensure people’s driving safety. In the expressway construction, has adopted the bored pile technology, not only improve the construction efficiency, but also improve the construction quality. This paper analyzes the application of the main construction technology of cast-in-place bored pile in expressway construction and discusses the common problems of bored pile optimization technology.
