摘要
在大部分高速公路桥梁建设过程中,总有一些地段处于复杂岩溶区,十分容易形成溶洞。这是一种比较常见的地质问题,该问题的存在会在一定程度上影响公路桥梁的建设质量和使用寿命。也正是因为复杂岩溶区的存在,大大提升了公路桥梁项目建设难度,必须采取针对性的措施。文章以安阳至新乡高速公路项目为主要研究对象,分析复杂岩溶区高速公路桥梁桩基溶洞施工技术,供相关人员参考。
During the construction of most highway bridges,there are always some sections in complex karst areas,which are very easy to form karst caves.This is a relatively common geological problem,which will affect the construction quality and service life of highway bridges to a certain extent.It is precisely because of the existence of complex karst areas that the construction of highway and bridge projects has been greatly improved,and targeted measures must be taken.In this paper,the Anyang Xinxiang Expressway Project is the main research object,and the construction technology of the bridge pile foundation karst cave in the complex karst area isanalyzed forreference.
