高速公路桥梁溶洞桩基施工研究

Study on Construction of Karst Cave Foundation of Expressway Bridges

随着社会经济的蓬勃发展,我国高速公路桥梁建设的速度也大幅提升。高速公路桥梁的施工建设一直是公路建设中的一大重点和难点,其直接影响着公路的使用寿命以及使用质量。在建设过程当中,溶洞的地貌特点经常会成为施工的难题,相应的对公路桥梁桩基施工的要求更高也更严格。通过对当前高速公路桥梁溶洞桩基施工中常见的问题进行汇总与分析,着重研究探讨溶洞桩基施工技术,提出相应措施,以供同行参考。

With the vigorous development of social economy, the speed of Expressway Bridge Construction in China has also been greatly improved. The construction of highway bridges has always been a major and difficult point in highway construction, which directly affects the service life and quality of highway. In the course of construction, the geomorphologic characteristics of karst cave often become a difficult problem in construction. Correspondingly, the requirements for construction of pile foundations of highway bridges are higher and stricter. Through the summary and analysis of the common problems in the construction of the karst cave pile foundation in the highway bridge, the construction technology of the pile foundation of the karst cave is studied and discussed, and the corresponding measures are put forward for the reference of the colleagues.
